Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
Mulama, Austine A; Mwabora, Julius M; Oduor, Andrew O; Muiva, Cosmas M (University of Nairobi, 2018)Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising semiconductor for phase change memory devices due to its thermal stability and low power consumption. The study investigated the effect of ... -
Optical properties of amorphous Se90-XIn10SbX thin film alloys
Muiva, Cosmas M.; Mwabora, Julius M; Sathiaraj, T.S; King, James G (University of Nairobi, 2016)Ternary thin film alloys of Se90-XIn10SbX (x = 1, 4, 10, 15 and 20) were synthesised by flash evaporation of the pre-melt quenched bulk samples under a vacuum of 10−5 Torr. Optical absorption analysis pointed to indirect ...
