Properties of wurtzite GaN MESFETs studied by two-dimensional full band Monte Carlo approach
The properties of a GaN MetalSemiconductor Field Effect Transistor were studied based on two-dimensional full band Monte Carlo simulations. The dependences of the distributions of the electric potential, electron concentration, electric field, drift velocity, and average electron energy on the gatesource voltage (VGS) and drainsource voltage (VDS) were obtained, then the characteristics of the drain current (IDS) versus the drainsource voltage (VDS) and the transconductance (Gm) versus VGS characteristics were determined. At and IDS is 5.03 A/cm, which is higher value. The Gm?VGS curve shows bell shaped and the maximum Gm is 112 ms/mm at and The current gain cutoff frequency (fT) is 98GHz at and
