The sustainable global energy economy: Hydrogen or silicon? [PDF]

open access: yes, 2008
A sustainable global silicon energy economy is proposed as a potential alternative to the hydrogen economy. This first visualisation of a silicon energy economy is based on largescale and carbon-neutral metallic silicon production from major smelters ...

Silicon Nitride in Silicon Photonics [PDF]

open access: yesProceedings of the IEEE, 2018
The silicon nitride (Si3N4) planar waveguide platform has enabled a broad class of low-loss planar-integrated devices and chip-scale solutions that benefit from transparency over a wide wavelength range (400–2350 nm) and fabrication using wafer-scale processes.

Silicon – single molecule – silicon circuits

open access: yesChemical Science, 2021
Single-molecule circuits using silicon contacts are robust, conductive, controllable, and highly reproducible in blinking experiments, with enhanced conductance in break-junctions owing to residual dangling bonds.

Spontaneous direct bonding of thick silicon nitride [PDF]

open access: yes, 1996
Wafers with LPCVD silicon-rich nitride layers have been successfully direct bonded to silicon-rich nitride and boron-doped silicon surfaces. A chemical - mechanical polishing treatment was necessary to reduce the surface roughness of the nitride before ...

Raman Spectroscopy and Spectral Signatures of AlScN/Al2O3

open access: yesMicromachines, 2022
III-V solid solutions are sensitive to growth conditions due to their stochastic nature. The highly crystalline thin films require a profound understanding of the material properties and reliable means of their determination.
