M. Tavares et al., The finite-temperature photoluminescence correlation function in semiconductor heterostructures, EUR PHY J B, 11(4), 1999, pp. 655-663
We report the inclusion of temperature effects on the Mahan-Nozieres-De Dom
inicis framework to study both many-body and temperature effects in photolu
minescence spectra of doped semiconductors. The electronic part of the corr
elation function characterizes the photoluminescence spectra. We have treat
ed the optical valence hole as a localized scattering potential center and
studied effects of the electron-hole interaction enhancement on the photolu
minescence spectra leading to the appearance of shake-up structures. We als
o have identified a term in the correlation function which represents the f
inite temperature contribution to the intensities of the shake-up structure
s. The method is used to study the magnetophotoluminescence of modulation-d
oped quantum wells with a weak periodic lateral potential.
