Abstract
This diode has an undoped GaN layer, an AlGaN layer (0<x<1)thereon, a Mg-doped p-type InGaN layer (0<y<1)having an island-like shape thereon, a metal electrodethereon, an anode electrodewhich is provided on the AlGaN layerand which is electrically connected to the metal electrodeand a cathode electrodewhich is provided on a part of the AlGaN layerwhich is located on the opposite side from the anode electrodewith respect to the p-type InGaN layer. In this diode, at a non-operating time, a two-dimensional electron gasis formed in the undoped GaN layerin the vicinity part of a hetero-interface between the AlGaN layerand the undoped GaN layerexcept a part below the p-type InGaN layer
