Electronic Raman Scattering In Silicon Glass

Brief Description

A novel approach at characterizing and manipulating enhanced photoemission in disordered and amorphous silicon glass.

Full Description

Researchers at UC Irvine, in collaboration with a coworker in Kazan Federal University, have leveraged vibrational Raman scattering to understand light emission in a heterogeneous, cross-linked silicon glass. They attributed the photoemission to electronic Raman scattering, enabled by the enhanced momentum of a photon within the nanostructured domains of their sample design. Capitalizing on this discovery, they demonstrated optical transitions over a wide spectral range, showcasing the promising potential of this technology in silicon-based semiconductor development and characterization.

Suggested uses

• Companies active in optoelectronics and semiconductors. 
• Industries utilizing semiconductor technologies for solar energy conversion, optical detection, and light emission. 
• Researchers developing novel methods and probes in optical spectroscopy.

Advantages

• Reconciles the poorly understood phenomenon of light emission in porous and nanostructured silicon. 
• Enables optical transitions over an ultrabroad spectral range, covering multiple spectral octaves. 
• Applicable to both organic and inorganic semiconductors by design.
