Abstract:
1. A diode comprising: a cathode; an anode; a plurality of semiconductor layers disposed between said cathode and said anode, said plurality of semiconductor layers forming a heterointerface between two of said plurality of semiconductor layers, and wherein said two semiconductor layers are formed of different materials, one material of said two semiconductor layers having a higher bandgap than a material of the other of said two semiconductor layers, with the semiconductor layer formed of the higher bandgap material being disposed (i) closer to a main portion of said anode and (ii) further from said cathode than the semiconductor layer formed of said other material; and a dielectric layer disposed between the semiconductor layer having the higher bandgap material and the main portion of said anode, the dielectric layer having one or more openings or trenches formed therein through which said anode projects into said at least said semiconductor layer having the higher bandgap material.
