X-ray diffraction is one of the most common and efficient ways to measure a superlattice structure. This dissertation displays the detail results for characterization of Ge〓Si〓/Si superlattices by x-ray diffraction (including x-ray small angle diffraction and double crystal diffraction). It was found, when the growth temperature is lower, the intensities of xray small angle diffraction peaks are modulated by a periodical function, which indicates that both sets of interfaces of the superlattice is highly flat; when the growth temperature is higher, the diffraction peak intensities are simply decay with the increase of diffraction vector, which indicates that one set of interfaces is highly flat but another is not; when the growth temperature is very high, the diffraction peaks are reduced more rapidly, which indicates that both sets of interfaces are not ideal.

本文详细介绍了用X-射线衍射（包括X-射线小角衍射和双晶衍射）方法对Ge〓Si〓/Si超晶格结构特性测试的结果，尤其是发现，当Ge〓Si〓/Si超晶格的生长温度较低时，X-射线小角衍射谱峰的强度随着衍射波矢的增加而周期性调制，表明超晶格的两套界面都十分平整；当生长温度较高时，Ge〓Si〓Si超晶格的X-射线小角衍射谱峰的强度随着衍射波矢呈简单的衰减变化，对应于超晶格内有一套界面不平整的情况；当生长温度进一步提高时，X-射线小角衍射峰明显减少，表明超晶格内两套界面都不理想。

On the other hand,interface reaction is weakened drasticallyon the interface between Co with sulfur-passivated GaAs(100)by CH3CSNH2 treatment,astable interface forms at the coverage of 8〓Ga atoms bonded with S at the surface exchangewith Co atoms and diffuse into Co matrix,which causes the formation of Co-S bonding.

In order to determine the fractal dimension of the interface, structures with different rotation radii are set in the transition region. By using above regulation, the number of surface molecules of each rotation structure with certain radius can be obtained, then correlate these molecule numbers with the corresponding radii, in a logarithmic coordinate system the asymptotic slope of the correlated curve is the fractal dimension of the liquid-vapor interface.

为了确定界面的分形维数，在气液过渡区中作出不同回转半径的结构，利用（2～5）/1.2r〓规则找出其中所包含的气液界面上的分子数，然后将这些分子数与回转半径关联，在双对数坐标中此关联曲线的渐近斜率便是气液界面的分形维数。

It was indicated that the effect of crystal orientation on interfacial stability is because of the different atomic bond number formed in the solidification of liquid atoms on different crystal planes, which affects the decrease of system energy, and affects the effective jump frequency of liquid atom migration to solid interface and solid atom migration to liquid, and finally affects the solute distribution in the front of liquid-solid interface and composition undercooling.

研究表明，晶体取向对凝固界面稳定性的影响是由于液相原子在不同晶面结晶面上沉积时形成的原子键不同，影响了系统自由能的降低，影响了液相原子迁移至固相界面上的有效跳动频率和固相原子迁移至液相中的有效跳动频率，影响了液固相界面前沿的溶质分布和成分过冷所致。
