Fourier transform infra- red (FTIR) measurement of the Si powders was performed on attenuated total reflectance (ATR) mode using a Cary 660 (Agilent Technologies) FT-IR system equipped with an MCT detector. All spectra were scanned from 650 cm−1 to 2000 cm−1 with resolution of 2...
The optical parameters of hydrogenated amorphous a-Si1−xGex:H layers were measured with focused beam mapping ellipsometry for photon energies from 0.7 to 6.5 eV. The applied single-sample micro-combinatorial technique enables the preparation of a-Si1−xGex:H with full range composition spread....
根据所使用的清洗步骤顺序，特别是最后一步，表面处理不仅强烈影响生长速率，而且强烈影响整体氧化物和Si/Sio2界面的性质，通过傅里叶变换红外光谱(FTIR)对薄氧化物层的结构质量进行了比较分析，并与不同的清洗程序所产生的影响有关，这些都是基于标准的RCA方法加上高频溶液蚀刻法，所得结果表明，红外技术能够理解所...

The interaction of CO with the cationic Lewis acid sites of transition-metal ion-exchanged zeolites Y was investigated by Fourier-transform infrared spectroscopy (FTIR) and temperature-programmed desorption (TPD) by Rakic et al.; disproportionation of CO was seen during its sorption and TPD [7]....
Comprehensive study of surface chemistry of MCM-41 using Si-29 CP/MAS NMR, FTIR, pyridine-TPD, and TGA A comprehensive study was conducted on mesoporous MCM-41. Spectroscopic examinations demonstrated that three types of silanol groups, i.e., single, (SiO)(3... XS Zhao,GQ Lu,AK Whittake...
The nu]C-C stretching mode of linear GeCSi has been identified at 1939.0 cm-1. The assignment is confirmed by the very good agreement between Fourier transform infrared (FTIR) measurements of frequencies and isotopic shifts and predictions of our quantum theoretical calculations....
(FTIR) spectroscopy data (Fig.1) showed that, up to week five, only encapsulated (CP5) isolates were recovered. At week six, both encapsulated (CP5) and non-encapsulated isolates were detected in the same sample, with only non-encapsulated isolates remaining after week six until the end ...
Cl and Eu. As shown in the XPS spectra (Fig.S8) of core-shell structured nanocomposites, the binding energy of C (1 s, 284.78 eV), (1 s, 288.65 eV); N (1 s, 399.3 eV); O (1 s, 532.45 eV); Si (2p, 103.35 eV); Cl (2p1/2, 209.25 eV...
