Silicon germanium (Si1-xGex) is a material with high mobility and relatively low bandgap making it an attractive candidate for the bottom subcell in a multi-junction solar cell. Optical constants of S1-xGex films grown on silicon substrates with germanium (Ge) compositions of 77%, 82%, 85...
Optical constants of Si1xGex films grown on silicon substrates are determined.Si1xGex films show similar optical properties with corresponding bulk materials.The absorption coefficients are three times higher in some wavelengths.The Ge composition of SiGe we obtained is more accurate than previous ...
Optical Constants of SiO2 Films Deposited on Si Substrates doi:10.1088/0256-307X/31/4/046401SiO2 films were deposited on single-crystalline silicon substrates by ion beam sputtering technology. Optical constants of SiO2 films are calculated from spectroscopic ellipsometry data, transmittance spectra and ...
The general features of the optical constants over the electromagnetic spectrum are relatively consistent throughout the literature. In particular, silica glass is effectively opaque for wavelengths shorter than 200 nm and larger than 3.5-4.0 microm. Strong absorption bands are observed (i) below 160...
Optical constants [n,k] of 30–300 nm SiO2 films, thermally grown on c-Si substrates, are obtained numerically from [R,T] data. The calculations are done a... DV Tsu - Journal of vacuum science & technology. B, Microelectronics and nanometer structures: processing, measurement, and phenome...
The lack of order in amorphous chalcogenides offers them novel properties but also adds increased challenges in the discovery and design of advanced functional materials. The amorphous compositions in the Si–Ge–Te system are of interest for many applic
Ideally the dielectric constants of the dielectric buffer layer and the analyte will be equal, i.e. εb = εa. If the thickness of the thin metal layer is such that kzm ⋅ dm≪1, the resulting symmetric configuration causes the same surface plasmon frequency to exist on both...
We introduce the refractiveindex.info database, a comprehensive open-source repository containing optical constants for a wide array of materials, and describe in detail the underlying dataset. This collection, derived from a meticulous compilation of data sourced from peer-reviewed publications, manufact...
