Temperature dependence of electron transfer in coupled quantum wells

Majumdar, Amlan; Choi, K.K.; Reno, J.L.; Rokhinson, L.P.; Tsui, D.C.

The temperature dependence of electron transfer between coupled quantum wells in a voltage tunable two-color quantum-well infrared photodetector (QWIP) was reported. It was shown that the electron transfer process is efficient only when interwell tunneling dominates. It was found that when thermoionic emission is substantial, electrons tend to accumulate in the shorter wavelength quantum well.
