Claim Text:
1. A method of fabricating an electronic device comprising; (a) growing an active layer of Ga (b) forming an Ohmic contact on a second side of the substrate; (c) forming a Schottky contact, metal-insulator-semiconductor structure or p-type semiconductor on the active layer; wherein (d) the substrate has a dislocation density of less than 10 (e) the substrate has electron concentration or an oxygen concentration higher than 10 (f) the active layer has an electron concentration or an oxygen concentration of Less than 10 (g) the active layer has a thickness greater than a thickness of the depletion region for any applied voltage within an operation range of the electronic device, and wherein the active layer has a concentration of sodium at least 100 times less than a concentration of sodium of the substrate, and the sodium concentration of the substrate is greater than 10
