Theory of the composition dependence of the band offset and sheet carrier density in the GaN/AlxGa1−xN heterostructure

Satpathy, Sashi Sekhar, 1956-; Popovic, Zoran S.; Mitchel, W. C. (American Institute of Physics, 2004)

We present a systematic study of the sheet carrier density and valence-band offset in the GaN/AlxGa1−xN(0001) heterostructure as a function of x from ab initio density-functional methods. We find that the calculated sheet ...
