Xd. Mu et al., Observation of an anomalously large blueshift of the photoluminescence peak and evidence of band-gap renormalization in InP/InAs/InP quantum wires, APPL PHYS L, 79(8), 2001, pp. 1091-1093
We have investigated polarization-dependent photoluminescence in InP/InAs/I
nP quantum wires directly formed on the top of InP substrates. With excitat
ion laser intensity we have observed an anomalously large blueshift of the
photoluminescence peak using a cw laser with extremely low intensities. We
have also observed evidence of band-gap renormalization. In addition, we ha
ve measured two-photon luminescence spectra and confirmed their dependence
on photoluminescence polarization. (C) 2001 American Institute of Physics.
