Scattering mechanisms of highest-mobility InAs/Al${}_x$Ga${}_{1-x}$Sb quantum wells

T. Tschirky, S. Mueller, Ch. A. Lehner +4

We study molecular beam epitaxially grown, undoped Al${}_x$Ga${}_{1-x}$Sb/InAs/AlSb quantum wells with different buffer and barrier designs and varying quantum well width. The highes…
