Quantum Confinement in Nanometric Structures

Chapter

Abstract

This paper discusses the quantum confinement effects in nanometric structures that form low dimensional systems. In such systems, each surface/ interface acts like a potential barrier, i.e. the wall of a quantum well, generating new energy levels. These levels are computed in a model that uses the approximation of the infinite rectangular quantum wells. The model is adapted for 2D, 1D and 0D systems, respectively. Different applications are discussed. The differences between the model results and the experimental data are proved to be of the same order of magnitude as the differences between the levels computed within the frame of infinite and finite quantum well approximations.
