Graphene transistors

The video tutorial explains the structure and functionality of a graphene transistor. It details the components, including the bottom gate, insulator, source and drain electrodes, and the top gate. The tutorial describes how electrical current flows through the highly conductive graphene sheet, which is a single atom thick. The gate's role in amplifying or limiting electron flow is discussed. The graphene transistor's ability to operate at 100 gigahertz, significantly faster than common silicon transistors, is highlighted. The video concludes with the importance of transistor arrays in forming integrated circuits or microchips.
