在用分子束外延法(MBE)生长Hg_(1-x)Cd_xTe合金系时要特别重视这种材料的下述特性:(1) 在150℃以上,组分值x为0.2～0.3的Hg_(1-x)Cd_xTe会很快分解并变得非常不一致;(2) 汞的粘附系数很低,小于0.03;(3) 汞蒸汽压很高。由于Hg_(1-x)Cd_xTe合金系的分解速度随温度降低而快速下
Special attention should be paid to the following properties of this material when growing Hg_ (1-x) Cd_xTe alloy by molecular beam epitaxy (MBE): (1) Hg_ ( 1-x) Cd_xTe decomposes very quickly and becomes very inconsistent; (2) the mercury adhesion coefficient is very low, less than 0.03; (3) the mercury vapor pressure is high. Since the decomposition rate of Hg_ (1-x) Cd_xTe alloy decreases rapidly with temperature
