Аннотация
Пленки диоксида олова, легированного сурьмой (ATO), были получены на стеклянных подложках методом центрифужного нанесения при скоростях вращения от 2000 до 3500 об/мин. Исследовано влияние скорости вращения на физические свойства пленок Sb-SnO2. Рентгенограммы пленок Sb-SnO2 демонстрируют тетрагональную структуру рутила. Морфология поверхности показывает однородный рост пленок со сферической структурой, а при более высоких скоростях вращения наблюдалась агломерация зерен. Пленки Sb-SnO2, полученные при 3500 об/мин, показывают оптимальное пропускание 82% в видимой области. Энергия оптической запрещенной зоны пленок Sb-SnO2 увеличилась с 3.23 до 3.46 эВ вследствие эффекта Бёрстайна-Мосса. Удельное электрическое сопротивление пленок SbSnO2 увеличилось с 2.80×10⁻ ⁴ до 3.86×10⁻ ⁴ Ом·см при увеличении скорости вращения с 2000 до 3500 об/мин.
