Abstract
The electron intervalley interlayer transfer through the confined X states of the AlAs barrier and the enhanced electron tunneling effect have been observed in the AlAs/GaAs (001) triple-barrier heterostructure. The effects of the lower X-valley confined states, the field-induced interlayer state mixing, and the quantum-well excited energy states are analyzed with the local density of states under the external bias, using the scattering theoretic Green’s function approach. The experimental results show good agreements with theory.
