GFET Tool simulates the electrical and thermal characteristics of a graphene field-effect transistor (GFET). The code uses the drift-diffusion approach to calculate the current vs. voltage behavior of the GFET, self-consistently with the temperature of the device. It can also output the carrier density, temperature profile, drift velocity, and electric field along the GFET channel. The code accounts for velocity saturation at high fields, Seebeck effect at contacts, and possible device breakdown due to thermal self-heating. Many parameters (dimensions, mobility, contact resistance) can be set by the user
