CdTe films were deposited by closed space sublimation from different CdTe:Bi targets (from non-doped up to 0.16at.%) previously sintered by the Bridgman method. X-ray diffraction measurements demonstrate that CdTe films are formed and Bi is incorporated. Electrical and optical characterizations show that thin films reproduce the bulk material behaviour with a decrease in resistivity and an increase in photoconductivity. Also a limit is found in the increase of photoconductivity properties versus Bi concentration. © 2006 IOP Publishing Ltd.
