Спин-орбитальные взаимодействия в полупроводниковых квантовых точках и кольцах
В монографии исследуются связанные состояния электрона в квантовых точках и кольцах, которые локализованы во внутреннем слое двойной полупроводниковой гетероструктуры. Квантовые точки и кольца рассматриваются как двумерные круговые нанообъекты с удерживающими прямоугольными потенциалами конечной глубины. Учитывается влияние на состояния электрона как спин-орбитальных взаимодействий Рашбы и Дрессельхауса, так и внешнего магнитного поля. Получены волновые функции и дискретные уровни энергии электрона, соответствующие различным соотношениям интенсивностей двух типов спин-орбитальных взаимодействий. Адресуется научным работникам, преподавателям, студентам и аспирантам, специализирующимся в области применения квантово-механических расчетов в физике полупроводников.
