“…Considering the large differences in thermal expansion coefficients between the Al 2 O 3 substrate and the Ag and AlN layers, the accumulation and subsequent relaxation of thermally-induced stress gradients in the NML upon heating could promote directional Ag migration. 20,32 Namely the relaxation of thermal stresses can be easily achieved at the free surface, but not at the interface. Indeed directional (inward) migration of Ag to the NML/substrate has not been observed in the present study.…”

“…Ранее авторами [6,8] экспериментально показано, что применение пористого кремния в качестве буферного слоя в гетероструктурах 3C−SiC/Si, позволяет снизить значение остаточных напряжений. Для получения выражений, описывающих остаточные напряжения в гетроструктурах 3C−SiC/por-Si необходимо ввести указанные ниже корректировки.…”
