This article investigates photoluminescence (PL) spectra of an In 0.22 Ga 0.78 Sb/GaSb single quantum well (SQW) in 10-160 K temperature range. Emissions associated with free exciton and free carrier recombinations were observed. Line-shape analysis of PL spectra was performed by means of a statisti
Piezomodulated reflectance (PzR) spectroscopy has been used to study the InAs/In 0.15 Ga 0.85 As quantum dots-in-a-well (DWELL) samples in the temperature range of 70-300 K. The optical transitions from ground state to excited states in InAs DWELL were observed. The heavy-and light-hole transitions
