Silver nanoparticles embedded in ZnO matrix were deposited onto fused silica substrates using high pressure (~40 Pa) d.c. sputtering techniques. The particle size in the films was tailored by varying the system pressure and substrate temperature, while the metal volume fraction was controlled by adjusting the relative time of sputtering of the targets. Blue-shift of the surface plasmon resonance peak...
CuIn(S x Se 1-x ) 2 films were synthesized by sulphurization of In/Cu stacked elemental layers deposited onto glass and Mo-coated glass substrates followed by selenization by graphite box annealing. The films, thus synthesized, were characterized by measuring electrical, optical and microstructural properties. The microstructure and hence the physical properties of...
Grain growth in CdTe films was studied by rapid thermal annealing of films prepared by co-deposition (at room temperature) of CdTe and CdCl 2 . Annealing conditions were varied to optimize the post-deposition heat treatment for obtaining CdTe films with larger grains. It was found that it is possible to obtain grains ~5 μm in size in CdTe films by the above techniques. Photoluminescence...
