В работе с использованием методов трёхмерной молекулярной квазистатики (пренебрегая влиянием температуры), а также модельных расчётов в рамках двумерной модели Френкеля - Конторовой молекулярной динамики выполнено моделирование сетки дислокаций несоответствия на границе медь/сапфир. Полученные результаты дают естественное объяснение отсутствию когерентной модуляции вблизи границы медь/сапфир, наблюдаемой в высокоразрешающей электронной микроскопии.

With the use of the 3D molecular quasistatic simulation (at zero temperature) and simulation in frame of 2D Frenkel-Kontorova model, we study the misfit accommodation at a copper/sapphire interface. Our results give a natural explanation of the apparent absence of coherency of the interface observed in the high resolution electron microscopy.
