Abstract :
The mechanisms for current conduction in the substrate of planar ion-implanted GaAs power MESFETs for wireless communication are investigated by 2D simulation. A properly doped p-buffer layer can eliminate the substrate conduction, but a too heavily doped p-buffer can reduce the saturation current (Idss) and the breakdown voltage significantly. Optimal design for the p-buffer of the MESFETs is described
