Localization model description of the interfacial dynamics of crystalline Cu and Cu64Zr36 metallic glass films.

摘要: Recent studies of structural relaxation in Cu-Zr metallic glass materials having a range compositions and over wide temperatures crystalline UO2 under superionic conditions have indicated that the localization model (LM) can predict time τα these from intermediate scattering function without any free parameters particle mean square displacement ⟨r2⟩ at caging on order ps, i.e., "Debye-Waller factor" (DWF). In present work, we test whether this remarkable relation between "fast" picosecond dynamics rate amorphous be extended to prediction local interfacial films. Specifically, simulate free-standing Cu64Zr36 Cu films find LM provides an excellent parameter-free for region. We also show Tammann temperature, defining initial formation mobile layer, estimated precisely both glass-forming solid condition DWFs region material interior coincide.
