This study explores the effect of the structural parameters of the confining potential and external magnetic field on the electronic properties of a double quantum wire (DQW) system. Using theoretical analysis and graphical representations, we investigate the effects of varying parameters such as structural parameters (µ and λ) on the confinement potential profiles, probability density distributions and energy spectra of DQWs. Furthermore, we investigate the effect of variation of the confinement potential, the Rashba spin-orbit coupling and the external magnetic field on the energy spectra and the local density of states of the system. The changes in the energy spectra and the local density of states of the system due to Rashba spin-orbit coupling, and the external magnetic field were highlighted. The shifts and variations in energy and in the local density of states were discussed in detail. Our research results provide valuable insights into possibility of using the structural parameters and the external magnetic fields for control the electronic properties of the double quantum wire system.

В этом исследовании изучается влияние структурных параметров ограниченного потенциала и внешнего магнитного поля на электронные свойства системы с двойными квантовыми проводами (DQW). С помощью комплексного теоретического анализа и графических представлений мы исследуем влияние изменяющихся параметров, таких как структурные параметры (μ и λ), на профили потенциала ограничения, распределения плотности вероятности и энергетические спектры DQW. Кроме того, мы исследуем влияние изменения потенциала ограничения, спин-орбитальной связи Рашбы и внешнего магнитного поля на энергетические спектры и локальную плотность состояний системы. Были выделены изменения в энергетических спектрах и локальной плотности состояний системы из-за спин-орбитальной связи Рашбы и внешнего магнитного поля. Подробно обсуждались сдвиги и изменения в энергии и локальной плотности состояний. Результаты наших исследований дают ценную информацию о том, как можно использовать индивидуальные структурные параметры и внешние магнитные поля для управления электронными свойствами системы двойной квантовой проволоки.
