HKSTP × Tatler Jan Issue — Keep Up Advertorial
6C Technology featured in the HKSTP × Tatler 'Keep Up' advertorial in the Jan 2026 issue, on diamond cooling the heart of a hot smart city.
Smart City Frontier
From AI speech engines and diamond semiconductors to structural analysis, design software and battery-swapping stations for electric vehicles, Hong Kong start-ups are building the smart cities of tomorrow.
Residents thrive when the systems beneath a city run intelligently and seamlessly: transport networks that move people sustainably and efficiently, secure communication channels that protect personal information, resilient buildings designed to withstand a changing climate, and semiconductors that support next-generation electronics. In Hong Kong, a new breed of innovators is strengthening these foundations, pushing the world towards a future where every metropolis can be smart.
Diamond Electronics: Life After Silicon
In a smart city, daily life relies on high-performance innovations — from the AI powering autonomous vehicles to data centres running next- generation cloud and edge computing, and devices delivering predictive, personalised services. None of this is possible without semiconductors, the essential ingredient in every electronic chip.
While silicon has long been the standard material used for semiconductors, 6C Technology is advancing the field with an alternative: diamond, which the company describes as “a supermaterial with extreme properties.” But this is no ordinary diamond. Using a proprietary Microwave Plasma Chemical Vapour Deposition (MPCVD) process with high-purity hydrogen, the team can configure and accelerate the growth of diamonds for industrial uses at commercial scale. These diamonds are 15× more effective at dissipating heat than silicon, and are deployed in critical compute electronics and quantum-related technologies to prevent thermal-overload breakdowns — permitting unrestrictive compute performance, durability, and energy efficiency of electronic systems.
By turning this breakthrough into real-world production, 6C is overcoming physics barriers to meet the demands of the advanced technologies that underpin the digital age.
