摘要：

The effect of electron-electron interactions on quantum well intersubband transition spectral linewidths is examined. It is shown that the effect of exchange interactions on absorption linewidths can be comparable in magnitude to observed absorption linewidths, so that previous assumptions about the origin of observed widths may need to be revised. The exchange interaction width mechanism involves differences in the in-plane momentum dependence of electron energies in the ground state subband and the excited state subband. These differences are primarily due to intrasubband exchange interactions in the ground state subband. © 1991.
