Abstract

space charge-limited current and Schottky behavior with improved ideality factor up to 0.38 mM Cu.

Enhanced room temperature ferromagnetism and green photoluminescence in Cu doped ZnO thin film synthesised by neutral beam sputtering

“…To overcome these issues, there is requirement of such dopant which does not show ferromagnetism. Cu-doped ZnO (ZnO:Cu) does not have ferromagnetic impurities due to the non metallic nature of Cu as well as its oxides are non ferromagnetic leading to form an intrinsic dilute magnetic semiconductor 22,23 . Mutual ferromagnetic-ferroelectric coupling is recently reported in Cu-doped ZnO 24 .…”

Photocatalytic properties of Cu-containing ZnO nanoparticles and their antifungal activity against agriculture-pathogenic fungus

“…For several years, two-dimensional ZnO particles have been attracting attention due to their physical and chemical properties. 9 The use of Cu as a dopant generates many changes in ZnO such as: (i) lattice distortion and morphological changes, 10 (ii) improvement in photocatalytic activity in comparison with pure ZnO, 11 (iii) increased energy conversion efficiency, 12 (iv) improvements in the visible light absorption range, 13 and (v) narrowing of the bandgap value. 14 Cupric oxide is a widely used material in many applications due to its p-type character, narrow bandgap (1.2 eV), and visible light absorption.…”

Physical Properties of Cu Doped ZnO Nanocrystiline Thin Films

“…ZnO can be manufactured by several technologies such as chemical vapor deposition, thermal evaporation, magnetically splatter, pulse laser deposition (PLD), chemical vapor deposition, and non-vacuum methods can be used, i.e. absorption and interaction of the SILAR gel spin coating, Pyrolysis methods 1,7,[10][11][12][13][14][15][16][17] . The PLD method is characterized by the other technologies, where in films were prepared by this method at low temperatures due to the increased energy of the lower particles in the laser column resulting from the relatively high deposition rates 16 .…”
