“…To further study the dynamic difference between the coalescence process of a-NPs and c-NPs at the same time, we prepared the thin film with both amorphous and crystalline PdSi NPs. When the diameter of the NPs is larger than 2.5 nm, the crystallization induced by irradiation would occur 45 . We thus applied the atomic resolution Cs-STEM to distinguish three different coalescence processes of a-NP, c-NP and amorphous crystalline NP (a-c-NP) pairs, and studied the crystallization influence on the NPs dynamics.…”

“…First of all, it concerns the state of ordering of atoms, which in extreme cases can be crystalline or amorphous. However, as shown in [16], the size changes near the threshold level does not affect the structure.…”

“…Авторами работы [16] зарегистрирован спонтанный фазовый переход наноразмерных частиц PdSi из кристаллического состояния в аморфное, вызванный только уменьшением формы наночастицы без приложения каких-либо внешних воздействии (рис.2). Такое поведение авторы работы объясняют с помощью классических представлений -из условия минима лизации свободной энергии Гиббса, которую они представляют как суперпозицию свободной энергии поверхности (возрастающей с ростом размера наноча с т и ц ы) и с в о б од ной энерг и и о б ъ е м ног о материала (уменьшающейся с ростом размера наночастицы).…”
