Pressure and temperature effects on magnetoelectric band energies in GaAs / InxGa1-xAs cylindrical quantum wires

2020 Cumhuriyet Science Journal  
Low-dimensional systems, consisting of GaAs / InGaAs heterostructures, have attracted considerable attention due to their many applications in optoelectronic and microelectronic devices. In the present work, the electron and the heavy-hole ground state energy in an InGaAs/GaAs cylindrical quantum well wires (CQWWs) is investigated with the consideration of geometrical confinement. The ground state energy was calculated as a function of hydrostatic pressure and temperature. Under the constant

These calculations are interpreted with graphics.
