Abstract:
The working principles of the hot-electron graphene base transistor (GBT) for analog terahertz operation have been investigated by means of a self-consistent Schrodinger-Polsson solver code. Its regions of operation are defined and discussed. With the help of a small-signal model, it is shown that the cutoff frequency does not depend on the quantum capacitance of the graphene layer, which on the contrary severely affects the intrinsic voltage gain, and that terahertz operation is possible.
