Direct Interband Light Absorption in Conical Quantum Dot

Abstract EN

In the framework of the adiabatic approximation, the energy states of electron as well as the direct light absorption are investigated in conical quantum dot.

Analytical expressions for particle energy spectrum are obtained.

The dependence of the absorption edge on geometrical parameters of conical quantum dot is obtained.

Selection rules are revealed for transitions between levels with different quantum numbers.

In particular, it is shown that for the radial quantum number transitions are allowed between the levels with the same quantum numbers, and any transitions between different levels are allowed for the principal quantum number.
