Abstract

In the framework of adiabatic approximation the energy levels and direct interband absorption of light in the falciform lens shaped quantum dot are studied. Analytical expressions for energy spectrum and wave functions of the electron are obtained. It has been shown, that the particle energy spectrum is equidistant, and dependence of energy on geometrical parameters has root character. Dependences of absorption coefficient and edge frequencies on geometrical parameters of a quantum dot are obtained in the strong quantization regime. Corresponding selection rules for quantum transitions are revealed.
