Claim 0:
1. An electronic device, comprising:
a buffer structure over a substrate;
a back barrier layer over the buffer structure, the back barrier layer including one of aluminum gallium nitride, aluminum nitride, indium aluminum nitride, and indium aluminum gallium nitride;
a gallium nitride layer over the back barrier layer;
a hetero-epitaxy structure over the gallium nitride layer;
a first transistor having a first drain, a first gate, and a first source, the first drain partially in the hetero-epitaxy structure, the first source partially in the hetero-epitaxy structure and spaced apart from the first drain, and the first gate over the hetero-epitaxy structure and between the first drain and the first source;
a second transistor having a second drain, a second gate, and a second source, the second drain partially in the hetero-epitaxy structure and coupled to the first source, the second source partially in the hetero-epitaxy structure and spaced apart from the second drain, and the second gate over the hetero-epitaxy structure and between the second drain and the second source; and
a hole injector structure having a doped gallium nitride structure and a conductive structure, the doped gallium nitride structure extending over the hetero-epitaxy structure, and the conductive structure partially over the doped gallium nitride structure.
