Quantum Structures of Advanced Materials

Abstract

In this chapter the fundamental optical properties of low dimensional semiconductor materials like quantum well, wire and dot will be explained from analytical points of view in addition to real application of those low dimensional materials to devices. At the beginning the analytical method of hetero junction will be explained which is a base of quantum structures. After that the density of states of low dimensional material will be calculated for free electron in materials which is important to understand the optical properties of real devices. The optical properties of each low dimensional material will be explained and readers can understand what the specific optical nature of each low dimensional material is. Finally in this section the real application of low dimensional material to laser will be introduced and advantage of the low dimensionality will be explained. Since many references are cited, readers can understand deeply the parts which are interested in through the references.
