https://wccftech.com/china-taps-in-graphene-technology-to-replace-silicon-based-chips-breaking-the-monopoly-with-10-times-the-performance/ "Graphene comprises an individual layer positioned "in a hexagonal lattice of carbon atoms." Graphene is two hundred times stronger than steel. The strength is unmatched compared to silicon. At the same time, thermal and electrical conductivity is better than copper, which would be essential in the development of not only semiconductor chips, but thermal heat dissipation, efficient batteries, and more. Lastly, graphene is lightweight, measuring less than one milligram per square meter" Related: Team develops graphene-based nanoelectronics platform https://phys.org/news/2022-12-team-graphene-based-nanoelectronics-platform.html TC Microchips Announces on the Brink of Graphene-based Chip Breakthrough https://markets.businessinsider.com/news/stocks/tc-microchips-announces-on-the-brink-of-graphene-based-chip-breakthrough-1034107130
