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. ...
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 ...
Does the Assumption of Exponential Arrival Distributions in Wireless Sensor Networks Hold?
(University of Nairobi, 2018)
Wireless Sensor Networks have seen a tremendous growth in various application areas despite prominent performance and availability challenges. One of the
common configurations to prolong the lifetime and deal with the ...
