ЭЛЕКТРОННАЯ СТРУКТУРА И ОПТИЧЕСКАЯ ПРОВОДИМОСТЬ ПОЛНОГО СПЛАВА ГЕЙСЛЕРА Fе2TiSn

Аннотация

Полный сплав Гейслера Fe2SnTi представляет интерес как дешевый и экологически чистый термоэлектрический материал для прямого преобразования тепла в электричество. В последнее время значительное количество работ было опубликовано в литературе, где его электронная структура изучалась методом теории функционала плотности. Однако разброс полученных данных настолько широк, от наличия псевдощели до предсказания запрещенной зоны шириной около 1 эВ, что невозможно сделать однозначные выводы об электронных свойствах данного соединения. В данной работе мы выполнили высокоточные расчеты электронной структуры сплава Гейслера Fe2SnTi с использованием метода GW0 и обнаружили, что это полупроводник с шириной запрещенной зоны 0,34 эВ. Для объяснения экспериментов по измерению оптической проводимости, при которой наблюдался металлический отклик, были исследованы различные дефектные структуры.
