<p>An enhancement mode gallium nitride (GaN) transistor with a Mg doped layer and a Mg growth interruption (diffusion barrier) layer to trap excess or residual Mg dopant. The Mg growth interruption (diffusion barrier) layer is formed by growing GaN, stopping the supply of gallium while maintaining a supply of ammonia or other nitrogen containing source to form a layer of magnesium nitride (MgN), and then resuming the flow of gallium to form a GaN layer to seal in the layer of MgN.</p> |
