They treated the valence electrons and the electrons in the ion core on the same footing. In a way similar to Seitz's cellular method, a sphere with a volume equal to that of a unit cell was drawn and periodic boundary conditions were applied on the surface. Furthermore another boundary condition was imposed in their calculation, namely, on the ground that the sphere as a whole is elec...             本文用Fermi-Thomas方法计算了金属的结合能。得到初步结果:金属的能量舆晶格常数的关系中,有一极小值。此极小值所对应的原子间距对重金属舆实验值相近,而对单价碱金属则理论值太小。所得结合能的数值较实验值大很多。作者认为这是由於F.T.方法应用到原子上所存在的误差所引起的,而不是在金属内应用的误差所引起的。 文摘来源          A theory is proposed for the impurity-induced tunnelling current which apparently constitutes the major part of the current observed in As and P doped germanium tunnel diodes. The experimental valley-orbit splittings of various donors in. germanium show-that the short range atomic fields of As and P are many times stronger than that of Sb and, for doping levels above 1019/cm3, can be equally or more effective in scattering than phonons. The possible mechanisms for tunnelling caused by impurity scattering ar...             这工作是对锗中杂质散射引起的隧道电流的理论分析。说明在高掺杂(～10~(19)厘米~(-3)时杂质散射隧道电流是重要的,可以与联系着声子的隧道电流比拟或更大。不同杂质的作用是不同的,AS和P比Sb的强。锗中杂质隧道过程主要是二级过程,由导带底穿入禁带的电子先被杂质场散射到对应于导带(0,0,0)谷的电子状态,然后,再在结势垒场的作用下跃迁到价带。提出了这种过程的理论,得到杂质隧道电流的表达式,说明只有处在势垒区中一定区域(大致是20左右厚度)中的杂质原子对这个过程有显著贡献。虽然导带底是各向异性的,但这过程的几率却几乎是各向同性的。在附录Ⅱ中还提供了一个在任意形式位垒下直接隧道过程的普遍理论。 文摘来源          The impurity-assisted indirect transition of n-type degenerate Germanium is a second order process. Electrons near the top of the valence band were excited to the (0, 0, 0) valley of the conduction band by the interaction with light and then scattered into the minimum of the conduction band by the short range field of impurity atoms. Using the second order perturbation theory, the absorption coefficient due to such processes was calculated. The fact that contributions of various donors are different a...             N型简并锗中杂质协助的间接光跃迁是个二级过程.价带顶附近的电子先受光的激发跃迁到导带的(0,0,0)谷,然后受杂质近程场的散射转入导带底.利用二级微扰理论计算了这种过程对光吸收系数的贡献.能说明不同的施主杂质的贡献是不同的,砷比磷的大. 文摘来源   << 更多相关文摘         相关查询: (valence low valence average valence variable valence chemical valence valence electron valence shell valence orbit valence stability valence bond antibody valence coordination valence  对查询结果不满意
