Energy Gap Dependence on the Hydrostatic Pressure and Temperature of GaAs Quantum Wire

In this study, we examine the energy gap dependence on the hydrostatic pressure and temperature with the existence of an intense magnetic field and Rashba spin–orbit interaction. First, we employ diagonalizing method to work out the Schrödinger equation. After that, we calculate the energy gap for a GaAs quantum wire. Our numerical outcomes illustrate that the energy gap dependence on the hydrostatic pressure and temperature of a GaAs quantum wire. We also focus on the effect of magnetic field and Rashba spin–orbit interaction on the curve of energy gap vs pressure/temperature.
