An analytic approach is presented for calculations of the electron tunneling escape time from a quantum well confined by ultrathin δ-like barriers. It is shown that the quasibound state decays exponentially and its lifetime depends strongly on well width and cladding barrier opacity.

Abstract
An analytic approach is presented for calculations of the electron tunneling escape time from a quantum well confined by ultrathin δ-like barriers. It is shown that the quasibound state decays exponentially and its lifetime depends strongly on well width and cladding barrier opacity.File in questo prodotto:
