Modulation-doped (Al,Ga)As/AlAs superlattice: electron transfer into AlAs

A modulation-doped superlattice of n-(Al,Ga)As and undoped AlAs has been grown by molecular beam epitaxy. At cryogenic temperatures, electrons transfer into the undoped AlAs layers and enhanced mobilities as high as 1000 cm2/Vs are observed for the first time. It is shown that by properly accounting...
