Abstract
Enhancement of light emission from HgCdTe due to surface patterning has been studied by means of photoluminescence (PL) spectroscopy. A triangular pattern of circular holes was etched into the CdTe layer grown on top of HgCdTe thin-film and multiple quantum well samples. Two different pattern lattice constants were used, giving lattice constant aG to emission wavelength ratios of 0.9, 1.2, and 2.1. The surface pattern was found to give 26%-35% enhancement in measured PL intensity.
