Thin films of Zn100-xCdxO with x = 0, 2, 4, 6 and 8 at% were deposited by electron beam evaporation technique on glass substrates. The structural, optical and electrical properties of Zn100-xCdxO films with x = 4 at% have been investigated as a function of annealing temperature. Only zinc and cadmium appeared in the as-deposited films, by annealing their oxides ... إقراء المزيد

THIS WORK PRESENTS THE STRUCTURAL AND OPTICAL FEATURES OF MAGNETRON CO-SPUTTERED AL–ZNO THIN FILMS. THE STRUCTURE OF THE FILMS HAVE BEEN CARRIED OUT USING BY X-RAY DIFFRACTION (XRD), SCAN ELECTRON MICROSCOPE (SEM) AND X-RAY FLUORESCENCE (XRF). THE OPTICAL CONSTANTS OF THE THIN FILMS HAVE BEEN DEPICTED IN THE WAVELENGTH RANGE 300–2500 NM USING SPECTROPHOTOMETRIC MEASUREMENTS. THE OPTICAL BAND GAP OF ... إقراء المزيد
