Electron scattering and electrical conductance in polycrystalline metallic films and wires: impact of grain boundary scattering related to melting point.

For electrical conductance in polycrystalline metallic films and wires, the reflection coefficient of electrons at grain boundaries is explored and found to be proportional to the square root of the melting points of metals. As validated by available experimental results, this exploration enables classical models to take an essential role in theoretically predicting the electrical conductance o...

GRAIN BOUNDARY DIFFUSION IN POLYCRYSTALLINE SILICON FILMS ON SiO2

The enhanced grain boundary diffusion in cw laser processed LPCVD polycrystalline silicon films on insulating SiC>2 has been investigated and the grain boundary diffusion coefficient D' for Phosphorus has been determined. Mesa diodes were fabricated in the large grain poly-Si films by standard photolithographic and etching methods and subsequent ion implantation. The electron beam induced curre...

Constrained Grain Boundary Diffusion in Thin Copper Films

Coherent phonon-grain boundary scattering in silicon inverse opals.

We report measurements and modeling of thermal conductivity in periodic three-dimensional dielectric nanostructures, silicon inverse opals. Such structures represent a three-dimensional "phononic crystal" but affect heat flow instead of acoustics. Employing the Stober method, we fabricate high quality silica opal templates that on filling with amorphous silicon, etching and recrystallizing prod...
