First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

The morphologies of the CdZnTe etch pits developed by four etchants including Nakagawa, Everson, EAg1 and EAg2 solutions are studied. The results show that the etch pits of EAg2 etchant on the (111) B surface are flat-bottomed. And the etch pits of Everson etchant on (111) B include flat-bottomed pits and pyramidal pits with different slant directions, while the positions of pyramidal pits don′t move as the surface layer is continuously removed.
