Abstract

Cu_xAg_1-xInSe₂ (CAIS) thin films were deposited by a hybrid magnetron sputtering/evaporation process over a range of x values. Cryogenic cathodoluminescence (CL) data was obtained from these thin films. Emission peaks were identified and spectrally-resolved images were recorded at these wavelengths. A power-dependent CL series was also recorded. Emissions were fairly uniform across the sample for AgInSe₂ (AIS) (x=0). As x increased, the emission became less uniform both in intensity and in spectral components. AIS showed no significant difference between grain and grain boundary emission, while some grain boundaries in CAIS with x=0 showed higher emission intensity than the grains. No reduction in emission intensity was seen from topmost surface features in AIS, as opposed to CIS. Cu _0.6Ag_0.4InSe₂ showed the largest variation in emission from grain to grain, while CIS showed the largest variation in emission from grain to grain boundary.
