Abstract

In this paper, the interband light absorption and photoluminescence of coupled vertical cylindrical quantum dots with double modified Pöschl–Teller potential in terahertz range made of InAs are studied. Expressions for the particle energy spectrum, wavefunction, absorption and PL coefficients and dependencies the geometrical sizes of quantum dot are obtained. The selection rules corresponding to different transitions between quantum levels are found.
