Theoretical Study of Phase-Shifted Quantum Beats in Time-Resolved LuminescenceSpectra from a Biased Asymmetric Double Quantum Well

摘要

Analytical expressions have been developed for time-dependent luminescenceintensities for a practically feasible asymmetric double quantum well under bias and numerically demonstrated to elucidate the characteristic of phase-shifted quantum beats. It is clear analytically as well as numerically that the magnitude of the tunneling interaction can be quantitatively estimated by the beat modulation depth.
