Abstract:
1. A semiconductor structure comprising: a semiconductor material layer having a doping of a same conductivity type throughout and located on a substrate; at least one first-type electrode having angled corners and conductively connected to said semiconductor material layer and having a bottommost surface located above a top surface of said semiconductor material layer; at least one second-type electrode conductively connected to said semiconductor material layer; and a plurality of non-uniform electric field regions located in said semiconductor material layer and around said angled corners of said at least one first-type electrode, wherein said at least one first-type electrode is at a first voltage and said at least one second-type electrode is at a second voltage that is different from said first voltage, wherein said at least one first-type electrode and said at least one second-type electrode are in contact with said semiconductor material layer.
