最近有一种新的材料——半磁性半导体,由于其新颖的光学及磁光效应引起了人们的广泛兴趣。Zn_(1-x)Mn_xSe即是一种宽带半磁性半导体材料。本文用升华法生长了半磁性半导体单晶Zn_(1-x)Mn_xSe。为了提高晶体质量和晶体中的Mn浓度,我们把材料的预合成同生长分开。预合成采用了合成烧结、研磨、打饼、烧结的过程,这样充分保证了生长原料的均匀性。生
Recently, a new kind of material, semi-magnetic semiconductors, has drawn great interest due to its novel optical and magneto-optical effects. Zn_ (1-x) Mn_xSe is a kind of wideband semi-magnetic semiconductor material. In this paper, semicrystalline semiconductor single crystal Zn_ (1-x) Mn_xSe was grown by sublimation method. In order to improve crystal quality and Mn concentration in the crystal, we separate the pre-synthesis of the material from the growth. Pre-synthesis using a synthetic sintering, grinding, fight the cake, sintering process, so fully guarantee the uniformity of the growth of raw materials. Health
