Precise measurements of the X-ray attenuation coefficient of crystalline silicon have been made in the energy range 25 to 50 keV. The results are compa-ed with Transmission Range : 1.2 to 15 μm (1). Refractive Index : 3.4223 @ 5 μm (1) (2). Reflection Loss : 46.2% at 5 μm (2 surfaces).

If λ is in nm, multiply by 10 7 to get the absorption coefficient in the units of cm-1. Additional optical properties of silicon are given in the page Optical Properties of Silicon. Optical absorption at 10.6 μm in silicon is mainly due to lattice absorption and free carrier absorption. 2013-03-02 4H-SiC.

Quantification of Hydrogen Concentrations in Surface and

This absorption is due to free carriers and approximately follows a Drude model, which is a shorthand for assuming the absorption coefficient (about 0.5 micron of the material will absorb 90% of the incident sunlight); the energy gap can be modulated to allow for near optimum conversion efficiency for sunlight; it can be alloyed with other elements (carbon, germanium) to create multi-junction structures with increased energy conversion efficiency for sunlight. Optical constants of SiO 2 (Silicon dioxide, Silica, Quartz) Gao et al. 2013: Thin film; n,k 0.252-1.25 µm We report high precision, high spectral resolution measurements of the absorption coefficient of silicon in the spectral region from 1.61 to 1.65 eV. Our data show a smooth absorption spectrum with no discernable features in this spectral region where structure has been reported previously. Our data and analysis suggest that the second indirect transition in silicon has yet to be detected in 1990-08-20 2009-04-24 1990-09-01 Silicon (Si) During the past few decades, silicon has been developed to be the world's most widely produced semiconductor material, and as such is the most readily available for use in infrared systems, producing consistently high purity and sufficiently large quantities and … The optical absorption coefficient of silicon has been measured at the HeNe near-infrared line (lambda = 1.152 ..mu..m) from room temperature to 1140 K. The results are compared with the previous less extensive data in the literature, and with the formulation given … The absorption coefficient of crystalline silicon is an important material parameter for a variety of applications in the field of photovoltaics, e.g., device simulations aiming at the prediction of energy conversion efficiencies or the analysis of luminescence measurements.
