✦ Synopsis

Grain growth in CdTe films was studied by rapid thermal annealing of films prepared by co-deposition (at room temperature) of CdTe and Cd& 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 ,um in size in CdTe films by the above techniques. Photoluminescence

studies were used to derive information on the film defect structure.
