Explosive crystallization mechanism of ultradisperse amorphous films [PDF]

, 1999
The explosive crystallization of germanium ultradisperse amorphous films is studied experimentally. We show that crystallization may be initiated by local heating at the small film thickness but it realizes spontaneously at the large ones.
