Abstract
A unipolar diode with low turn-on voltage includes a subcathode semiconductor layer, a low-doped, wide bandgap cathode semiconductor layer, and a high-doped, narrow bandgap anode semiconductor layer. A junction between the cathode layer and the anode layer creates an electron barrier in the conduction band, with the barrier configured to produce a low turn-on voltage for the diode. A unipolar diode with low turn-on voltage includes an nsubcathode semiconductor layer, a low-doped, wide bandgap cathode semiconductor layer, and an nnarrow bandgap anode semiconductor layer. Again, a junction between the cathode layer and the anode layer creates an electron barrier in the conduction band, with the barrier configured to produce a low turn-on voltage for the diode.
