First working graphene semiconductor could lead to faster computers
Researchers have created a functional semiconductor from graphene for the first time, creating the possibility of computer chips with greater performance and efficiency
A working, scalable semiconductor has been created from graphene for the first time, potentially paving the way for a new type of computer with greater speed and efficiency than today’s silicon chips. Now, Walter de Heer at Georgia Tech in Atlanta and his colleagues have created graphene with a bandgap and even demonstrated a working transistor, an on/off switch that either prevents or allows current to flow through it. De Heer wasn’t available for interview at the time of writing, but said in a statement that the electrical properties of a graphene semiconductor were far better than those of silicon chips.
