Pressure-induced transformations in amorphous Si-Ge alloy

Viscosity and elastic constants of amorphous Si and Ge

The biaxial modulus and coefficient of thermal expansion of ion-beam-sputtered amorphous Si and Ge thin films were determined from curvature changes induced by differential thermal expansion. Viscous flow was measured by stress relaxation and was found to be Newtonian. The viscosity increased linearly with time as a result of structural relaxation, and its isoconfigurational activation enthalpy...

Hydrogen Effects on an Amorphous Fe-Si-B Alloy

HYDROGEN interaction with amorphous alloys has Ribbons (,25-mm thick) of amorphous Fe80B11Si9 were been studied extensively due to both scientific and technoused for this research. The ribbons were produced by planarlogical interest. In the framework of a more comprehensive flow casting and were kindly supplied by AlliedSignal Inc. investigation of hydrogen interaction with amorphous and (Parsi...

Effect of mixed Ge/Si cross-linking on the physical properties of amorphous Ge-Si-Te networks

Hydrogen Induced Si Surface Segregation on Ge-Covered Si(001)

Using Fourier transform infrared-attenuated total reflectance spectroscopy in conjunction with hydrogen adsorption to probe surface layer composition, we observe a reversible place exchange between Ge and Si on Ge-covered Si(001) when the surface is dosed with atomic H at elevated temperatures. First-principles calculations confirm a thermodynamic driving force for this place exchange. To expla...
