Abstract
Interfacial reactions of Ni/amorphous Si(a-Si) multilayers are studied by means of transmission electron microscopy (TEM) and cross-sectional transmission electron microscopy (XTEM). Transformation from a crystalline to an amorphous structure has been observed in as-deposited Ni/a-Si multilayers with small modulation periods. This phenomenon is suggested to be due to interdiffusion-induced solid state amorphization which is facilitated by the high density of interface in the shorter modulation period multilayers. A thermodynamic and kinetic explanation is given for this phenomenon.
