Photoconductivity study of ZnSiP(2) and CdSe:Cu by a computer-controlled spectrometer.
Instead of scanning the photoconductivity spectra continuously, a special computer-controlled experimental setup has been designed that enables step by step scanning and allows the photoresponse to be measured for a desired amount of time at each wavelength. With the help of this technique, it is possible to detect the contribution from the slow component of photoconductivity. This helps to resolve the finer details of the spectrum. Photoconductivity spectra of ternary compound ZnSiP(2) and commercially available CdSe:Cu were obtained using this technique. The results reveal structural details not reported before.
