Ag and Sn Nanoparticles to Enhance the Near-Infrared Absorbance of a-Si:H Thin Films
Silver (Ag) and tin (Sn) nanoparticles (NPs) were deposited by thermal evaporation onto heated glass substrates with a good control of size, shape and surface coverage. This process has the advantage of allowi...

Photoluminescence study of GaAs thin films and nanowires grown on Si(111)
Mg-doped GaAs nanowires have been grown by molecular beam epitaxy on a partially Au-coated Si(111) substrate by the vapor–liquid–solid mechanism. Outside the coated areas, a thin film of GaAs was grown epitaxi...
