Acoustoelectric effects in very high-mobility $p$-SiGe/Ge/SiGe heterostructure at low temperatures in high magnetic fields

I. L. Drichko, V. A. Malysh, I. Yu. Smirnov +4

The contactless Surface Acoustic Wave (SAW) technique was implemented to probe the high-frequency (ac) conductivity in a high-mobility $p$-SiGe/Ge/SiGe structure in the integer qua…
