Особенности определения энергии формирования вакансии в 4d-переходных металлах из первых принципов

В статье представлено исследование температурной зависимости энергии формирования вакансии в чистых ГЦК 4d-переходных металлах Ag и Pd с использованием теории функционала плотности. Особенностью работы является использование экспериментальных значений параметров решетки для соответствующих температур. В работе обсуждаются различные вклады в энергию формирования вакансий и показано, что все они могут играть важную роль. Показано, что тепловое возбуждение оказывает существенное влияние на энергию формирования вакансий при высоких температурах. Показана возможность существования компенсационного эффекта, то есть одновременного изменения вкладов свободной энергии и энергии формирования вакансии в ГЦК 4d-переходных металлах Ag и Pd, которые исследовались из первых принципов. Учет вкладов свободной энергии колебаний и теплового расширения электронов в зависимости от температуры позволяет получить качественную картину эффекта теплового расширения. Рассчитанные энергии формирования вакансий хорошо согласуются с предыдущими теоретическими и экспериментальными исследованиями. Эффект взаимной компенсации различных вкладов в энергию формирования вакансии позволяет объяснить постоянное значение энергии формирования вакансии при любой температуре и оправдывает пренебрежение температурной зависимостью при моделировании свойств.
