The Future of Electronics: A Breakthrough in Semiconductor Technology

TLDRResearchers have developed a new semiconductor material that can revolutionize computer chips, enabling them to run significantly faster. By stacking transistors vertically and using graphene-based devices, heat dissipation can be improved. However, the main challenge is the lack of a band gap in graphene. Scientists have overcome this by growing graphene on silicon carbide wafers, creating a new semiconductor called semiconducting epigraphene (SEG). With 10 times higher electron mobility than silicon, SEG promises faster chips with less heat dissipation. The manufacturing process is also compatible with conventional techniques. However, there are still technical hurdles to overcome before mass production.
