Effective-Mass Approximation for Electrons in Ultrathin Heterolayers
Abstract
It was shown that the usually employed model of rectangular potentials in the effectiveness equations generally fail for ultrathin layers of width of the order of the lattice constant. There are additional terms. which play minor role for thick quantum wells and barriers. that may have drastic influence on electron states in semiconductor nanostructures with ultrathin layers. The terms are defined with details of the microscopic structure of heterointerfaces. It was shown that allowance for these terms may turn a barrier layer into an effective quantum well binding electrons, and vice versa.
