【Abstract】 A study on the etching and passivation of CdSe wafers in the preparing process of CdSe detectors has been made by measuring the I—V curves and the ?ray spectra. The results indicate that the surface leakage current can be decreased only when proper etching and passivation have been employed, and meanwhile electric noise can also be suppressed and consequently the energy resolution of CdSe detectors can be improved.更多还原
