WebThe refractive index of silicon was measured at room temperature over the range 1.1–2.0 μ by autocollimation in an ~12° wedge. The image was observed by sweeping it across a slit in front of a lead sulfide cell whose output was displayed vertically on an oscilloscope while the sweep frequency was displayed horizontally. The problems of measuring the … WebA model for the refractive index of amorphous silicon for FDTD simulation of photonics waveguides. Abstract: This paper presents an analysis of the material quality influence for …

WebHydrogenated amorphous silicon (a-Si:H) is a suitable material for the realization of planar waveguides to route and modulate the optical signal. a-Si:H can be deposited by plasma-enhanced chemical-vapor deposition (PECVD) on almost any substrate at temperatures below 230 °C, thus preserving compatibility with any microelectronic technology. WebThe method is illustrated with the analysis of transmittance data of very thin amorphous silicon films. The method allows retrieving physically meaningful solutions for films as … WebJun 15, 1989 · Optical measurements were performed from 0.5 eV to 3 eV in the temperature range 293–973 K on hydrogenated silicon thin films. The thicknesses of the films were chosen to obtain an accurate optical gap E g and static refractive index n 0.For a given sample, opposing variations in E g and n 0 are observed with measurement … healing through horses abiquiu nm
