Segmenting silicon waveguides at the subwavelength scale produce an equivalent homogenous material. The geometry of the waveguide segments provides precise control over modal confinement, effective ...

Abstract: We investigated the correlation between the temperature coefficient of elasticity (TCE) and Fourier transform infrared (FT-IR) absorption spectra of SiO 2 for SAW devices. The measurement ...

The only argument against crystalline Si as the ideal PV material both now and in the future pertains to the fourth criterion. That is, the availability, collection, and manufacture of crystalline Si ...

Amorphous silicon nitride (SiN x) thin films are widely used in modern microelectronics and also as thermal barrier materials in combustion engines. The structure and thermal conductivity of amorphous ...

Silicon dioxide (often called silica) is the main compound found in sand. It is an example of a substance with a giant covalent structure . It contains many silicon and oxygen atoms.

A critical challenge for flexible biomedical implants is in the development of materials and structures that enable intimate coupling to biotissues with long-term stability. The results presented here ...
