Abstract:
1. An electronic device comprising: a substrate; a plurality of two-terminal switching devices disposed on the substrate, wherein each two-terminal switching device comprises: the energy difference between a Fermi level of the first conductive material and the lowest energy level of a conduction band of the broad band semiconducting material is not greater than about 0.3 eV; the band gap of the broad band semiconductor is at least about 2.5 eV and the carrier concentration in the broad band semiconductor is less than about 10 the carrier concentration in the second conducting material is at least about 10 the work function magnitude of the second conductive material is at least about 0.6 eV greater than the work function magnitude of the first conductive material; and the energy barrier between the lowest energy level of the conduction band of the p+ or p++ conducting material and the lowest energy level of the conduction band of the broad-band semiconductor material is about 0.3 eV or less.
