Position Expectation Value and Oscillator Strength of a Biased Asymmetric Quantum Well
Abstract
The change in the position expectation values of an electron in the first three quasibound states of the structure as a function of the external (biased) voltage is calculated. At the resonance voltage, the most probable position to find an electron in the second and third quasibound states lies in the barrier separating the two wells, and these two states interchange their identities, meaning that the ground state of the narrow well becomes the first- excited state of the wide well and vice versa. Keywords: Quantum well, Biased asymmetric, Oscillator strength, Position expectation, Resonance, State parties.
