Рассчитана ширина запрещенной зоны для ряда одноатомных и двухатомных полупроводников Sn, Ge, Si, С, BN(c), SiC((3)(F43m), 2H-SiC(P63mc), A1N, GaN. Метод позволил получить значения ширины запрещенной зоны практически с экспериментальной степенью точности. На примере дефекта вакансия–кислород (А-центр) показано, что развитый метод может быть использован также для расчета как локализованных состояний (энергии глубоких уровней дефектов в кристалле), так и электронных свойств наноструктур.</p></abstract><trans-abstract xml:lang="en"><p>Within the framework of the density functional theory, the method was developed to calculate the band gap of semiconductors. Calculation of the band gap for a number of monoatomic and diatomic semiconductors demonstrated that the method gives the value of the band gap of almost experimental accuracy. An important point is the fact that the developed method can also be used to calculate both localized states (energy deep-level of defects in crystal), and electronic properties of nanostructures.</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Xiao Zheng et al. // Phys.
