Abstract

With a detailed analysis of the Bloch wave properties of one-dimensional infinite crystal, we find the exact analytical solution of the quantum confinement states in quantum well with infinite barrier. Based on the analytical solution, we calculate the complete electronic structure of quantum well with arbitrary geometries. The calculation results demonstrate that the transitions only occur between specific pairs of sub-bands. It also shows that the band edge state plays an insignificant role in the optical properties, although it is the most distinguishing feature of the quantum well.
