摘要
本文报道了利用分子束外延技术在GaAs(211)B衬底上生长Hg1-xCdxTe/CdTe异质结,并通过VanderPauw(VdP)方法测量P-Hg1-xCdxTe外延薄膜在不同温度及磁场下Hall系数和电导率,采用最小二乘法对实验数据下行拟合,得到了混合导电机制下电子、重空穴和轻空穴的迁移率及载流子浓度.
Abstract CdTe/Hg1-xCdxTe heterostructure materials grown on GaAs (211)B by MBE are reported. Temperature and magnetic-field dependences of a Hall coefficient and conductivity of p-type Hg1-xCdxTe epitaxial films are determined by Van der Pauw method. The mobility and carrier concentration such as electron,heavy and light hole are gained through the least Square fitting.
