ABSTRACT:
A semiconductor device has a heterostructure including a first layer of semiconductor oxide material. A second layer of semiconductor oxide material is formed on the first layer of semiconductor oxide material such that a two dimensional electron gas builds up at an interface between the first and second materials. A passivation layer on the outer surface stabilizes the structure. The device also has a source contact and a drain contact.
