摘要

We have observed a temperature insensitive and an unusual blueshift of photoluminescence peak energy in ten periods self-organized InAs quantum dots superlattice. The net temperature dependence of PL wavelength for samples with 3, 4 and 5 monolayer ten periods InAs quantum dots superlattice, respectively, are 0.15, 0.13 and-0.17 nm/°C, respectively. The temperature dependence of the InAs quantum dots shows a significantly different trend when the InAs layer thickness is smaller (redshift) or larger (blueshift) than around 4 ML.
