Plasmonic modification of CdTe thin films by gold nanoparticles: Methods, difficulties and solutions
Au nanoparticles were incorporated into CdTe thin films by three methods. Spray pyrolysis and sputtering methods yield plasmonic effect in CdTe layer. Spin coated HAuCl4 solution and air annealing substantially remove CdTe layer. The processes between HAuCl4 and CdTe in the air heat treatment were analyzed.
