Abstract

Vertical stacks of electrically confined quantum wires were demonstrated in devices with large areas. Multiple current plateaus and strong differential conductance oscillations were observed at above liquid nitrogen temperatures because of interlevel cascade transition of carriers. Our simulation results for charge transport, as well as interlevel infrared photoresponse red-shift, due to lateral electric field confinement show good agreement with experimental data.
