Fabrication and Characterization of Cu-doped ZnO Films using rf Reactive Magnetron Sputtering
ZnO thin films have emerged as an interesting research area owing to its useful properties. Recently, lots of attention have been attracted to doped ZnO with Cu atom due to its favourable potential in semiconductor devices. Pure and Cu-doped ZnO (CZO) thin films were deposited on the glass, p-GaN/AI...

ZnO thin films have emerged as an interesting research area owing to its useful properties. Recently, lots of attention have been attracted to doped ZnO with Cu atom due to its favourable potential in semiconductor devices.

The crystal structure, optical properties, surface morphology and electrical properties were investigated by using X-ray diffraction (XRD), ultraviolet-visible (UV-VIS) spectrophotometer, atomic force microscopy (AFM) and Hall measurement with four-point Van der Pauw configuration respectively.
