LIGHT ABSORPTION BY FREE CHARGE CARRIERS DURING ELECTRON SCATTERING ON AN ALLOY DEFECT IN SEMICONDUCTOR QUANTUM WIRES

In quasi-one-dimensional structures, as the width of the quantum wire decreases, the scattering rate of electrons due to lattice disorder increases. This increase explains the increase in light absorption by free carriers as the width of the semiconductor wire decreases. When the energy of the photon is greater than the distance between different subzones, the photon-absorbing electron is simultaneously scattered and moves to the transition region to other subzones. In the article, the role of light absorption in low-dimensional systems and scattering due to the irregularity of the alloy and the roughness of the boundary is determined in other mechanisms, as well as the interaction between the electrons of low-dimensional systems and intense sound waves. is to study the effect
