Abstract :
Some sputtering processes of GaAs(Ti) onto c-GaAs have been carried out in order to obtain thin films as candidates to be intermediate band photovoltaic materials. This work presents the results obtained in the study of the absorptance, from transmittance and reflectance responses, in samples obtained at different conditions of temperature and power during the sputtering deposition.
