Structural, electrical, and magneto-optical characterization of paramagnetic GaMnAs quantum wells
M. Poggio, R. C. Myers, N. P. Stern +2
Growth of GaMnAs by molecular beam epitaxy is typically performed at low substrate temperatures (250C) and high As overpressures leading to the incorporation of excess As and Mn in…
