Установлены параметры, характеризующие проявление слабой локализации, антилокализации и кроссовера между ними. Определены квантовые поправки к проводимости графена в единицах e2/h = 38,64 мкСм для различных соотношений между характерными временами сбоя фазы (расфазировки) и спин-орбитального рассеяния. Установлено, что при относительно большом времени спин-орбитального рассеяния, не менее 10–10 с, оно не влияет на поправку к проводимости, и ее значение определяется временем расфазировки и временами междолинного и внутридолинного рассеяния. Влияние спин-орбитального рассеяния заключается в подавлении слабой антилокализации. Оно приводит к перевороту спина электрона проводимости при упругом рассеянии, интерференционная картина слабой локализации усложняется за счет перемешивания спиновых состояний. Знак квантовой поправки зависит от того, какое спиновое состояние дает больший вклад.</p></abstract><trans-abstract xml:lang="en"><p>In this paper, the patterns of manifestation of weak localization and antilocalization in graphene with enhanced spin-orbit interaction, as well as in a topological insulator with a gap in surface states induced by magnetic impurities are studied. The parameters characterizing the manifestation of weak localization, antilocalization and crossover between them are established. Quantum corrections to the conductivity of graphene are determined in units of e2/h = 38.64 μS for various ratios between the characteristic dephasing time and spin-orbit scattering time. It has been established that with a relatively long spin-orbit scattering time, not less than 10–10 s, it does not affect the correction to conductivity and its value is determined by the dephasing time and the times of intervalley and intravalley scattering. The effect of the spin-orbit scattering is to suppress weak antilocalization. It leads to a spin flip of the conduction electron during elastic scattering, and the interference pattern of weak localization becomes more complicated due to the mixing of spin states. The sign of the quantum correction depends on which spin state contributes the most.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>графен</kwd><kwd>дихалькогениды переходных металлов</kwd><kwd>топологические изоляторы</kwd><kwd>слабая локализация</kwd><kwd>антилокализация</kwd><kwd>магнетосопротивление</kwd><kwd>спин-орбитальное взаимодействие</kwd><kwd>фаза Берри</kwd></kwd-group><kwd-group xml:lang="en"><kwd>graphene</kwd><kwd>transition metal dichalcogenides</kwd><kwd>topological insulators</kwd><kwd>weak localization</kwd><kwd>antilocalization</kwd><kwd>magnetoresistance</kwd><kwd>spin-orbit interaction</kwd><kwd>Berry phase</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Белорусского республиканского фонда фундаментальных исследований (грант Ф23МЭ-038).</funding-statement><funding-statement xml:lang="en">The work was supported financially by the Belarusian Republican Foundation for Fundamental Research (grant Ф23МЭ-038).</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Mingsheng X., Tao L., Minmin S., Hongzheng C.
