Tomm Epitaxial thin film CuGaSe 2 and CuInSe 2 samples grown on GaAs substrates with varying [Cu]/[Ga,In] ratios were studied using positron annihilation Doppler-broadening spectroscopy and were compared to bulk crystals. We find both Cu monovacancies and Cu-Se divacancies in CuInSe 2 , whereas, in CuGaSe 2 , ... [Phys. Rev. B 86, 064102] Published Mon Aug 06, 2012
