Theory of electronic and optical properties for different shapes of InAs/In0.52Al0.48As quantum wires

•We are interested for InAs/In1−xAlxAs quantum wires.•We present a method for energy spectra and wave function calculations.•The method is based on the coordinate transformation.•The influence of the parameters introduced is studied on the optical properties.

In this work, we propose an efficient method to investigate optical properties as well as their dependence on geometrical parameters in InAs/InAlAs quantum wires. The used method is based on the coordinate transformation and the finite difference method. It provides sufficient accuracy, stability and flexibility with respect to the size and shape of the quantum wire. The electron and hole energy levels as well as their corresponding wave functions are investigated for different shape of quantum wires. The optical transition energies, the emission wavelengths and the oscillator strengths are also studied.
