Optical properties of amorphous Se90-XIn10SbX thin film alloys
(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 ...
Angle resolved photoemission study of surface states on the Pt(997) vicinal surface
(University of Nairobi, 2010)
One-dimensional atomic chains can be synthesized on stepped surfaces and the electronic structure of the high vicinal surface plays an essential role in determining the physical properties of atomic chains grown on top of ...
Effects of Substrate Radial-Position Relative to the Sputter-Gun Axis on the Electrical, Optical and Structural Properties of ZnO Thin Films Deposited by Reactive Direct Current Magnetron Sputtering
(University of Nairobi, 2018)
ZnO thin films were deposited using reactive direct current (dc) magnetron sputtering on glass
substrates placed at seven variable radial positions (-1, 0, 1, 2, 3, 4 and 5 cm) relative to the
sputter-gun (target) axis. ...
Perpendicular magnetic anisotropy in Mn2VIn (001) films: An ab initio study
(University of Nairobi, 2017)
First principles study of the magnetic anisotropy of Mn2VIn (001) films show perpendicular magnetic anisotropy (PMA), which increases as a function of the thickness
of the film. Density functional theory (DFT) as implemented ...
Compositional and Thickness Effects on the Optical Properties of Zinc– Doped Selenium–Antimony Thin Films
(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 ...
