Abstract:
1. A semiconductor junction comprising: a first material comprising a metal or a semiconductor; and a second material, the second material in contact with the first material and wherein said second material comprises a semiconductor; in which a surface of said second material has a periodically repeating structure configured to cause electron wave interference formed with a plurality of indents with dimensions selected to reflect a probability wave of an electron from a bottom of an indent so that said wave interferes destructively with a probability wave of an electron reflected from a surface, wherein each said indent has a depth selected to increase apparent electron work function, wherein the depth of each said indent is less than approximately 10 nm and the width of each said indent is less than approximately 1 μm, thereby causing built in potential of said junction to change with a change in work function.
