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.

Homogeneous,highly crystalline Se and Te nanowires were prepared by a chemical solution process using selenious acid and orthotelluric acid as precursor materials.

采用化学液相反应，以亚硒酸或者原碲酸为原料，合成出尺寸均匀、高结晶度的硒、碲纳米线。

Low valent selenium and telluronium compounds have high reducing selectivity to be used to form carbon-hydrogen bonds as special reducing reagents.

低价硒、碲化合物具有良好的还原选择性，可用于多种碳-氢键的形成，碲叶立德和α-芳硒基取代的胂叶立德均可发生Wittig型反应，是形成碳-碳双键的重要方法。

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.

对碲锌镉晶体常用的Nakagawa、Everson、EAg1和EAg2四种腐蚀剂在碲锌镉材料（111）晶面上的腐蚀坑坑形进行了研究，结果发现，EAg2腐蚀剂在（111）B面上的腐蚀坑为平底坑，Everson腐蚀剂在(111)B面上产生的腐蚀坑包括平底坑和带有不同倾斜方向坑底的三角锥形坑，进一步的研究还表明，三角锥形坑并未沿着坑底的倾斜方向向下延伸。

Moreover, the nanorods of cobalt tellurides and nick tellurides were successfully prepared.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
