Ab initio study of the structural, vibrational and thermal properties of Ge2Sb2Te5
(International Journal of Computational Materials Science, 2015-05-12)
The structural, vibrational and thermal properties of hexagonal as well as cubic Ge2Sb2Te5 (GST) have been calculated from first principles. The relative stability of the possible stacking sequences of hexagonal GST has ...
Stability Investigation in the Optical Properties of Thermally Evaporated Ge5Se95-x Znx Thin Films
(University of Nairobi, Kenya, 2015)
Selenium-based chalcogenides are useful in telecommunication devices like infrared optics and threshold switching
devices. The investigated system of Ge5Se95-xZnx (0.0 ≤ x ≤ 4 at.%) has been prepared from high purity ...
Role of bismuth and substrate temperature on the optical properties of some flash evaporated se100-x bix glassy system
(University of Nairobi, Kenya, 2015)
Chalcogenide glasses are very important in the modern technology especially selenium-based. These
glasses are sensitive to electromagnetic radiation useful in the infrared optics. The study investigated the effect of ...
