Optical and Electrical Properties of Iodine Doped n-Type ZnSe Crystals
Languages of publication
We have studied the electrooptical properties of ZnSe single crystals doped with iodine by diffusion at high temperature. The obtained samples are highly conductive. The luminescence at 300 K (RT) is dominated by well known self activated orange emission. At 30 K the blue and orange emission is observed. The ratio of the blue emission peak intensity to the deep level one is much greater for the iodine doped samples than for the undoped intentionally ones.
