Abstract

In this chapter we study quantum states of Double Quantum Wells, DQW, and hydrogen-like molecules. Using the quantum chemistry definition of covalent bond and the virial theorem, we discuss molecular states in DQW and its relation with the quantum effects of splitting, anticrossing and hybridization of energy levels. The results give new ideas of "molecule-like" systems in artificial semiconductor heterostructures of nanometric dimensions. The concentration and proportions of the elements involved in the semiconductor heterostructures are experimentally controlled and represented by the geometric parameters of the DQW and the effective masses of the electrons or charge carriers. Therefore, to some extent, the properties and quantum phenomena of the "molecule-like" DQWs could be controlled with different purposes, which is not possible for natural molecules.
