Successful p-type ZnO thin films have been reported by depositing it on semi insulating GaAs substrates by Pulsed Laser Deposition (PLD) technique. The PLD samples were subsequently subjected to Rapid Thermal Annealing to achieve the required doped ZnO. X-ray Diffraction, Atomic Force Microscopy and Van der Pauw Hall measurements were performed on the annealed samples and compared with as-deposited...
Zinc oxide-silica (ZnO/SiO 2 =20:80, molar ratio) nanocomposites consisting of ZnO nanoparticles embedded in a dielectric matrix were prepared by a sol-gel technique (spin coating). Optical transmittance, Raman effect and photoluminescence measurements of the composites indicated effective capping of the ZnO nanoparticles (radii 1.4-1.5 nm) in the host showing practically no variation of particle...
