Estrutura de espectro dos portadores em filmes de superfícies congruentes

Abstract

The aim of this work is to investigate the structure of the electronic spectrum of a uniform congruent surface film (FSC) model along the y-axis. Bibliographic researches were made, referring to dimensional quantification (QD), classification of films, general method of investigation of films of variable thickness and technological possibilities. Deduction and resolution of the secular equation and discussion of approximation methods are carried out. The general differential equation theory with periodic coefficients and the perturbation theory are used. The results of the numerical calculations of the secular equation (left part of this equation), are in agreement with the wave function. These results are also confirmed according to the zero order approximation method.
