一些实验事实表明,非晶态半导体的最近邻关系与晶态相近,对晶态半导体结构的了解是讨论非晶态半导体结构模型的基础.最常见的半导体结构是硅、锗的金刚石结构,每个原子有四个最近邻,组成四面体.可以取这种四面体作为模型的结构单元.其它半导体在形成非晶态时,其键长和键角也常常与它的晶态结构相近,如一些硫属玻璃.
Some experimental facts show that the nearest neighbor relationship of amorphous semiconductors is similar to the crystalline one, and the understanding of the crystalline semiconductor structure is the basis for discussing the amorphous semiconductor structure model.The most common semiconducting structure is silicon and germanium diamond structure, each The four nearest neighbors of atoms form a tetrahedron, which can be taken as the structural unit of the model. Other semiconductors, when formed into amorphous states, often have similar bond lengths and bond angles to their crystalline structures, Some chalcedony glass.
