Effects of impurity factor on the physical and transport properties for Ga1-xAlxAs quantum wire in the presence of Rashba spin-orbit interaction

There is a need to get familiarized with a systematic and precise approach to study the energy dispersion and ballistic conductance in a Ga1-xAlxAs quantum wire. We have employed parabolic confinement in this work. The combined impacts of Rashba spin orbit interaction (RSOI), external electric field, magnetic field, and Aluminium concentration on energy dispersion and conductivity in a Ga1-xAlxAs quantum wire have been explored. The Energy eigenvalues and eigenvectors are quantified using the diagonalization method and the transport properties are computed by Landuer-Bttiker formalism. It is noticed that the external electric field, magnetic field, Rashba spin-orbit interaction, and Aluminium concentration (impurity factor x) alter the energy spectra and conductivity. Hence, these parameters significantly affect the physical and transport properties.
