Abstract : the effect of correction of self - consistent potential on electronic structure in simple cubic nanocrystal particles is calculated by means of the green ' s function method in the tight - binding approximation, taking only the nearest neighbor matrix elements into account. the numerical results show that the electronic energy spectrum is shifted, the chemical potential is not equal to the atomic energy level, the electronic density at each lattice point is changed, and the variation of electronic density at surface lattice point is the largest

In order to improve the properties of materials, one needs to understand the structural relationship between interface and matrix of the materials, such as interface atomic structure, misfit dislocation, chemical bond structure, stress field distribution, composition segregation etc. there are tremendous research works on the grain boundary and interface structures during last century and the sophisticated theory about grain boundary and interface, i. e. coincidence site lattice and 0 - lattice theories had been developed simultaneously
眾所周知，材料的宏觀性質是由其微觀結構所決定的，因此，為了改善材料的宏觀性能我們有必要弄清楚材料的界面與基體之間的結構關系，如界面的原子結構、失配位錯、化學鍵合、應力場的分佈等等。在上世紀，人們已對晶界和相界面結構進行了大量的研究，同時，相關的理論如「重位點陣」和「 o -點陣」理論也發展成熟。 -
