  2. 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

    文摘:在緊束縛近似下，只計及最近鄰的矩陣元，採用格林函數計算了自洽勢修正對簡立方納米晶體顆粒的電子結構的影響，發現電子能譜發生了移動，化學勢不等於格點原子能級，各格點的電子密度也發生了變化，其中以表面格點的電子密度變化最大。
