Resonant Tunneling through a HgTe/Hg(1-x)Cd(x)Te Double Barrier, Single Quantum Well Heterostructure

摘要

Resonant tunneling has been demonstrated through a double barrier, single quantum well Mercury Telluride/Mercury- (x) Cadmium (1-x) Teluride heterostructure for the first time. Negative differential resistance is observable at room temperature, exhibiting a 1.4:1 peak to valley tunnel current ratio. The observation provides direct evidence for the existence of the proposed intrinsic interface state. Keywords: Mercury compounds, Tellurides.
