| dc.description.abstract | In this work post-growth annealing effect on CdSe/SiO2 thin films grown by rf-magnetron co-sputtering technique was investigated. Annealed samples were characterised by Raman scattering, grazing incidence X-ray diffraction and room temperature photoluminescence. The nanocrystals (NCs) size changed from 15 to 5 nm by varying the annealing temperature from 550 to 400 degrees C Evaporation of Se at high temperatures was invoked to explain this phenomenon. Fowler-Nordheim tunnelling mechanism was found to be responsible for carrier transport for samples with bigger CdSe NCs sizes, and which showed better photovoltaic properties. | por |
