2D-subband spectra variations under persistent tunneling photoconductivity condition in tunnel delta-GaAs/Al structures

S. E. Dizhur, I. N. Kotel'nikov, V. A. Kokin +1

2DEG states of Al/$\delta$-GaAs structures were investigated in the persistent tunneling photoconductivity (PTPC) regime at low temperatures. "Thickening" of the unoccupied subbands to…
