The crystals of znse monocrystal grown via physical vapor transport ( pvt ) results higher cost and complicated procedures under congruent sublimation condition . therefore , a new chemical vapor transport ( cvt ) method was designed to grow znse crystals in our investigations . the compound ( nh4 ) 3zncl5 was employed as a transport agent in cvt method for the first time 受znse过窄的一致升华范围限制,物理气相输运( pvt , physicalvaportransport )技术生长znse单晶需要复杂的程序,因此我们选择化学气相输运( cvt , chemicalvaportransport )技术作为生长znse单晶的主要技术,并作了一定的改进。
