在由两个不同介电常数的交替层组成的周期性分层系统中,找到了点电荷电势的精确表达式。我们考虑了这种势的最有趣的极限情况。得到了超晶格中同一层电子和空穴形成的激子的能谱、束缚能和基态半径。 [忽略俄语文本]。
An exact expression is found for the potential of a point charge in a periodic layered system, consisting of alternating layers with two different values of the dielectric constant. The most interesting limiting cases for this potential are considered. Energy spectrum, bound energy, and the ground state radius of the exciton, which is formed by an electron and a hole, belonging to the same layer of the superlattice, are found.
