1. A layered structure comprising:
a substrate in [100] crystal orientation or a substrate having a plane with a miscut up to an angle of 20° with respect to a [100] crystal orientation;
a crystalline bixbyite oxide layer in [111] orientation that is directly on the substrate with no intervening layers between the crystalline bixbyite oxide layer and the substrate; and
a metal-containing layer crystallographically matched to the crystalline bixbyite oxide layer.
