Pressure-induced amorphization and an amorphous–amorphous transition in densified porous silicon

Nature, 2001
Crystalline and amorphous forms of silicon are the principal materials used for solid-state electronics and photovoltaics technologies. Silicon is therefore a well-studied material, although new structures and properties are still being discovered. Compression of bulk silicon, which is tetrahedrally coordinated at atmospheric pressure, results in a ...

Crystalline–amorphous and amorphous–amorphous transitions in phase-change materials

Journal of Non-Crystalline Solids, 2009
Abstract The transition from the crystalline state to amorphous state and back has been studied in the particular case of the GeSb2Te4 phase-change material by a computer simulation procedure. Modelling at the nanoscale indicates specific structural characteristics, especially the multiplicity of the amorphous phase as opposite to the uniqueness of ...

Photoinduced phase transformations in amorphous ZnSe thin films: amorphous-to-amorphous and amorphous-to-nanocrystalline transitions

Thin Solid Films, 2003
Abstract Photoinduced characteristics of amorphous (a-) ZnSe thin films at 10 and 300 K have been investigated using real-time photoluminescence (PL) and X-ray diffraction. The structural phase of as-deposited film is evaluated to be predominantly amorphous with uniformly distributed nano-scale crystallites, and the optical energy gap and complex ...

Hall effect in amorphous Si:H and amorphous Si:H/amorphous Ge:H superlattices

Applied Physics Letters, 1988
The sign anomaly in the Hall coefficient observed in substitutionally doped amorphous Si:H and amorphous Ge:H is also found in amorphous Si:H/Ge:H superlattices. The size of the Hall mobility in the superlattice is comparable to the Hall mobility in amorphous Si:H and amorphous Ge:H.
