我们采用ＭＯＣＶＤ外延技术首次在ＧａＡｓ（１００）和（１１１）衬底上成功地生长了ＭｇＳｅ单层薄膜．利用Ｘ射线衍射技术观察到了它的ＮａＣｌ结构、纤锌矿结构和闪锌矿结构三种相结构，并首次实验测量出了闪锌矿结构ＭｇＳｅ的晶格常数
We have successfully grown MgSe monolayers on GaAs (100) and (111) substrates for the first time using MOCVD epitaxy. The three phase structures of NaCl, wurtzite and sphalerite were observed by X-ray diffraction. The lattice constant of the sphalerite MgSe was measured for the first time
