Herzinger, The differences between lineshapes in the E, Thus, at least a part of the observed differences between these datasets can be related to the evaluation of measured data. Optimized Fabry-Perot-type SOI resonators exhibit high finesse even in … A. Woollam, J. Appl. The results by measuring the contact angle on the surface confirmed that the surface of the O2 plasma-treated np-Si layer was hydrophilic. B. Johs, B. C. M. Herzinger, SPIE, 15. Bond and grind back silicon-on-insulator (“BGSOI,” we use “SOI” throughout the paper) structure contains a buried thermal oxide (BOX) layer separating the substrate (handle) wafer from the thin (“active,” ACT) Si layer, called the device layer in the semiconductor industry. J. The data for the above graph is given below. W. Karstens, T. J. Madison, Proc. The optical properties of silicon have been determined from 0.2 to 6.5 eV at room temperature, using reflectance spectra of silicon-on-insulator (SOI) and ellipsometric spectra of homoepitaxial samples. I attached silicon reflection spectrum in 200-1200nm range. D. Redfield, J. Appl. P. Y. Yu and Cells, 4. Assessing possible genuine differences of measured samples is beyond the scope of the present study. D. B. Leviton, and Rev.

Our measurements of extinction using SOI samples covered the 2.25–3.2 eV range; a comparison with selected results from literature is shown in Fig. Selecting this option will search all publications across the Scitation platform, Selecting this option will search all publications for the Publisher/Society in context, The Journal of the Acoustical Society of America, Uncertainty analysis for the coefficient of band-to-band absorption of crystalline silicon, Temperature dependence of the reflectivity of silicon with surface oxide at wavelengths of 633 and 1047 nm, Parameterization of the optical functions of amorphous materials in the interband region, Ellipsometric determination of optical constants for silicon and thermally grown silicon dioxide via a multi-sample, multi-wavelength, multi-angle investigation, Refractive index of silicon and germanium and its wavelength and temperature derivatives, https://doi.org/10.1103/PhysRevLett.106.030801, https://doi.org/10.1016/j.solmat.2008.06.009, https://doi.org/10.1016/j.tsf.2014.03.056, https://doi.org/10.1016/0925-3467(92)90015-F, http://www.intechopen.com/books/show/title/modern-aspects-of-bulk-crystal-and-thin-film-preparation. Astrophysical Observatory. For this, we fabricated the np-Si layer on a p+-type silicon substrate and modified the surface wettability of the np-Si layer with oxygen (O2) plasma treatment. The changes in the reflectance spectra of the hydrophilic-treated np-Si layer were more noticeable than those in the untreated np-Si layer. M. Cardona, Fundamentals of Semiconductors, This option allows users to search by Publication, Volume and Page. We then compared the changes in the reflectance spectra of the O2 plasma-treated np-Si layer that had been exposed to various organic vapors with that of the untreated np-Si layer.
