The amount of Si-Si bonding in CVD oxynitride usually represents a small fraction of the total silicon (<5%) and we show that, in this case, the subtractive method of determination is inadequate due to the uncertainty in the values obtained from typical elemental analysis (with Rutherford ...
Keywords:silicon;directbonding;FTIR;XPS 1 引言 硅/硅直接键合是将两片镜片抛光的硅片经过表面清洗、活化处理、室温贴合及高温热处理等手段而实现一体化的新技术,虽然起步较晚,但发展极为迅速,目前已得到了广泛的应用[14]。但对其键合工艺、界面性质、键合机理等的研究还并不成熟,有待作进一步的探讨,使其从实验...
We investigate the two lowest single-particle hole states in the double quantum dots made of two vertically coupled Ge/Si nanoclusters (quantum-dot molecules), using a six-band \mathbf{k\,{\bm\cdot}\, p} model. A bonding-antibonding ground-state transition is observed with an increasing int...

Studies on Si-O bonding in silicate and aluminosilicate glasses based on SiKβ emission X-rays 来自 Semantic Scholar 喜欢 0 阅读量: 48 作者:S Sakka,A Senga 摘要: The Si Kβ X-ray emission spectra of silicate and aluminosilicate glasses and crystals have been measured with an X-ray ...
In previous studies, this phenomenon has been attributed to the higher O-S bonding energy compared to that of the Si-S bond27,39. However, we believe that the poor hydrophilicity of the Si wafer is the main reason underlying the impossibility of direct growth of MoS2 crystals on nonoxide ...

Atropisomers are important organic frameworks in bioactive natural products, drugs as well as chiral catalysts. Meanwhile, silanols display unique properties compared to their alcohol analogs, however, the catalytic synthesis of atropisomers bearing sila
The key fabrication steps are as follows: (a) forming the N type SiC drift region by epitaxy and doping; (b) forming the N type Si drift region on the SiC region by doping and bonding process; (c) the multiple photolithography and etching; (d) forming the stepped oxide layer; (e) ...
