The press hall of Xian Guang Research Institute felt like a heart concentrating the pulse of the global technology industry. Unlike the tremors confined to academic or industrial circles during past technological breakthroughs, the audience gathered here today included CEOs, chief technology officers, senior analysts, financial media reporters from top global tech companies, and countless eyes fixed on the venue through live‑stream lenses. The air was thick with a special tension blending skepticism, anticipation, and a sense of witnessing history. Everyone vaguely sensed that today might not be an ordinary product launch, but a moment when a technological epoch could begin.
Xiuxiu stood backstage, gazing through side curtains at the sea of dark‑clad figures and flashing camera lights below. Wearing a sharply tailored dark suit, subtle makeup, and a calm demeanor, only the depths of her always keen, hawk‑like eyes flickered with a sparkle hard to completely suppress—belonging to a trailblazer. In her hand she gently held a palm‑sized black card, simple yet full of technological aesthetics. It felt weighty, not physically, but in the hope of an entirely new era it carried—painstakingly nurtured from laboratory beakers and reaction chambers, finally crystallized here. This was "Xian Guang·First Light", the world's first commercially released artificial intelligence computing acceleration card based on carbon‑nanotube transistors.
Her thoughts drifted back several years to that exhilarating night when the first carbon‑based chip tape‑out succeeded. Then, the weak yet stable waveform of the ring oscillator, like the first fire lit in a dark wilderness, proved the feasibility of carbon‑based integrated circuits. However, the distance from feasibility to commercialization was far longer and more rugged than from zero to one.
The first mountain was **yield**. Early tape‑out results, though functional, had pitifully low yields, often struggling to maintain even a few percent. Slight unevenness in carbon‑nanotube density, orientation, or purity on wafers would be drastically amplified during subsequent complex integrated‑circuit manufacturing, causing large‑scale device failure. This wasn't merely a materials‑science issue, but an extreme challenge to the entire semiconductor fabrication process chain. They needed to develop entirely new chemical‑mechanical polishing (CMP) processes for carbon‑tubes' unique surface properties, design more precise doping and annealing flows to optimize transistor performance, even redefine defect‑detection standards and tools. Leading her team like the most patient craftsmen, Xiuxiu adjusted one parameter at a time, conquered one process node after another, raising yield from single digits, bit by bit to over ten percent, thirty, fifty... until now, under strictly controlled design rules and specific product lines, it could stably exceed seventy percent—sufficient to support commercial‑scale production. Every tiny improvement came from hundreds of failed experiments and countless sleepless nights.
Next was tempering **performance and stability**. Initial carbon‑based transistors, though showing extremely high intrinsic carrier mobility (meaning theoretically faster switching speeds), often saw performance drastically reduced when integrated into large‑scale circuits due to contact resistance, parasitic effects, and unique quantum effects at nanoscale (like ballistic transport, quantum tunneling). They needed to dive into atomic‑scale optimization of metal‑electrode‑to‑carbon‑nanotube contact interfaces, design novel three‑dimensional interconnect structures to reduce signal delay and crosstalk, and establish a complete set of simulation, modeling, and testing standards tailored for carbon‑based chips. Simultaneously, the electrical stability, thermal stability, and radiation resistance of carbon‑based materials under long‑term operation required extremely rigorous verification. They simulated various extreme environments, conducted aging tests lasting tens of thousands of hours, ensuring this tiny acceleration card could operate stably and reliably for years in real data centers.
The ultimate aim of all these arduous journeys, and the core focus of today's launch event, was carbon‑based chips' theoretically disruptive **energy‑efficiency** advantage.
Xiuxiu's gaze returned to the "First Light" acceleration card in her hand. Its core was no longer silicon, but a transistor network composed of billions of orderly‑aligned semiconducting carbon nanotubes. Compared to silicon‑based transistors, carbon nanotubes' extremely high carrier mobility and minimal intrinsic capacitance meant electrons traveled faster, encountered less resistance, requiring lower fundamental energy loss for the same computing task. Additionally, carbon nanotubes' inherently quasi‑one‑dimensional structure granted stronger gate control over channels, enabling complete transistor switching at lower voltages, further significantly reducing dynamic power consumption. Moreover, carbon‑based materials' excellent thermal conductivity allowed heat generated during high‑efficiency operation to dissipate faster, reducing performance throttling and extra cooling energy due to overheating.
Theory was beautiful, but transforming theoretical advantage into tangible, quantifiable commercial product performance was the real test.
Stage lights focused, music softly began. Xiuxiu took a deep breath, pressing down all memories and emotions, stepping steadily onto the stage center scorched by countless gazes.
She skipped lengthy pleasantries, diving directly into the topic. The giant circular screen behind her lit up, displaying the anatomical structure and core parameters of the "Xian Guang·First Light" acceleration card.
"Ladies and gentlemen, colleagues across the industry," Xiuxiu's voice, transmitted via microphone, filled the hall clearly and coolly, "today, we stand here not merely to launch a new computing product. We stand here to demonstrate a new possibility—a path beyond existing frameworks toward a more efficient, more intelligent future."
She raised the acceleration card in her hand; under spotlights, the black card gleamed with elegant luster. "This is 'Xian Guang·First Light,' our first commercially available AI computing acceleration card built on carbon‑nanotube transistor technology. Its mission is to redefine the boundaries of computing energy efficiency."
The large screen behind her began switching, displaying a series of benchmark test data verified by third‑party authoritative institutions. As row after row of comparative data clearly presented, the audience erupted with uncontrollable gasps and whispers.
While executing mainstream AI inference tasks (like image recognition, natural language processing), providing identical computational throughput (TOPS, trillions of operations per second) as the current market's top silicon‑based AI acceleration cards, **the typical power consumption of 'Xian Guang·First Light' was only one‑tenth of the latter's!**
Ten‑fold improvement in energy efficiency!
What did this mean? It meant that under the same power consumption, data centers could deploy ten times the computing capacity; meant edge‑computing devices constrained by power and thermal dissipation could achieve unprecedented AI performance; meant training and deployment costs of large‑scale AI models would plummet drastically; meant on the road toward larger, more complex artificial intelligence applications, a huge energy bottleneck had been broken!
Observing the shocked, incredulous, then fanatical expressions below, Xiuxiu continued letting data speak, showing energy‑efficiency comparisons under different loads, precision requirements—all invariably pointing to that astonishing advantage. She explained the innovative work they'd done in carbon‑nanotube purity control, threshold‑voltage regulation, low‑power circuit design, and efficient packaging‑thermal‑dissipation to achieve this breakthrough.
"This is not a proof‑of‑concept in the laboratory," Xiuxiu emphasized, tone carrying irrefutable confidence. "'First Light' has completed all necessary reliability tests and received initial strategic customer orders (including the largest domestic cloud service provider and a top‑tier autonomous‑driving company). It is about to step out of the laboratory into the real world, empowering all kinds of intelligent applications."
She announced the price—higher than top silicon‑based products yet highly competitive considering its enormous energy‑efficiency advantage. She presented the future technology roadmap, hinting at higher‑performance, higher‑integration carbon‑based chips on the way.
As the launch segment concluded, entering media Q&A, the atmosphere almost boiled over. Questions came like rapid‑fire—technical details, supply‑chain security, ecosystem building, impact on traditional semiconductor industry...
Xiuxiu stood on stage, composed and methodical, answering each question clearly. Her figure appeared resolute and powerful before the giant screen. She clearly knew that from today onward, a new technological branch would formally establish itself on the global semiconductor industry arena—a powerful player based on carbon, wielding extreme energy efficiency as its weapon. She not only personally pushed carbon‑based chips from laboratory to commercial market, but also opened a door for the entire information industry toward the "post‑Moore's Law" era.
Her career reached a dazzling height. She was no longer the engineer who returned from the Netherlands determined to break through DUV lithography, nor the technical leader who led her team to conquer EUV, scaling High‑NA peaks. At this moment, she was one of the initiators of an entirely new technological epoch. Using her wisdom and perseverance, she not only broke through silicon's physical limits, but also ignited the first, most crucial beam of dawn for humanity's next leap in computing capability—the dawn of carbon‑based computing.
After the event concluded, backstage, she received a brief message from Mozi in Shanghai: "Light of the Era." Soon, Yue'er also sent congratulations from Stockholm, attaching a photo of the Nobel medal placed beside the "Xian Guang·First Light" acceleration card, caption: "Formulas and light will ultimately illuminate the same future."
Reading these messages, Xiuxiu's face revealed a relieved yet powerful smile. She knew that personal peaks were always built on collective climbing. And the commercial dawn of carbon‑based computing was merely another conquered precipice on their "String Light" journey. Ahead, there were still grander vistas awaiting their shared exploration.
