Abstract
A method for measuring tunneling escape time has been developed by monitoring transient current response, arising from the escape of electrons out of a quantum well in a three-barrier, two-well heterostructure. The measured tunneling escape time shows ssU-shaped dependence on bias with a broadened minimum, unambiguously indicating the resonant feature of tunneling escape through a double-barrier resonant-tunneling structure.Keywords
