Photoluminescence (PL) spectroscopy is a powerful optical characterization technique that can determine properties of semiconductors. In this project, I will calibrate a temperature-dependent photoluminescence spectroscopy (temperature-dependent PL) setup by analyzing the PL spectra of a gallium arsenide (GaAs) quantum well. To do this, I will study quantum effects and use the software Igor Pro. Results on GaAs will be used to determine whether or not the instrument’s thermometers are correctly calibrated. Following the GaAs study, I will research an antimony trioxide sample with temperature-dependent PL to see if I can gain insights into whether the material can host quantum emitters, which are sources of single photons necessary for quantum computing technologies.
