CBE and CVD were performed in an ultra-high vacuum (UHV) system. The background pressure was kept at 1 × 10-10 mbar. The Au was deposited by MBE on a hydrogen terminated Si substrate with a surface te...
We investigated carrier-relaxation dynamics of femtosecond laser annealed (FLA) polycrystalline silicon (poly-Si). The correlation between morphology and electrical properties of poly-Si after femtose...
Synthesis, characterization, and application of nanoporous materials based on silicon- or halogen-containing spiroketal and spirothioketal polymers
Tetra(trimethylsilyl)-9,10-anthraquinone spiroketal polymers
2010/10/14
Organic microporous materials based on silicon-containing spiroketal and spirothioketal polymers were synthesized via a 1,3-dioxol-forming polymerization reaction between 1,1a,4,4a,5,5a,8, 8a-octahydr...
Evaluation of Outermost Surface Temperature of Silicon Substrates during UV-Excited Ozone Oxidation at Low Temperature
Evaluation Outermost Surface Temperature Silicon UV-Excited Ozone Oxidation Low Temperature
2010/9/17
Using ultraviolet (UV)-excited ozone gas, we prepared high-quality SiO2 films that can be used as gate dielectric films on poly-silicon or silicon wafers without sample heating. The UV-excited ozone g...
Study of surface exfoliation on crystalline silicon induced by Co-implantation of He and H ions
crystalline Si He and H ion implantation surface blistering and exfoliation bubbles growth
2009/8/14
Crystalline n-type Si (100) wafers were implanted at room temperature with
160 keV He ions to a fluence of 5×1016cm－2 or 40 keV H ions to a fluence of 1×1016cm－2, singly or in combination, followed ...
Surface morphology of He-implanted single-crystalline silicon
crystalline silicon He ion implantation He bubble Cavities blisters morphology
2009/8/14
Single-crystalline Si (100) samples were implanted with 30 keV He2+ ions to doses ranging from 2.0×1016 to 2.0×1017ions /cm2 and subsequently thermally annealed at 800℃ for 30min. The morphological ch...
Use of Silicon Substituents in the Syntheses of Natural and Non-natural Molecules

摘要 Trimethylsilyl groups have been used in our research as a director as well as a bulky and lipophilic group in our quest for natural and non-natural molecules.
硅表面含二茂铁基团自组装单分子膜制备及电流-电压关系测量（Ferrocenyl Self-assembled Monolayer on Silicon Surfaces: Preparation and Current-Voltage Measurement）
硅 单分子膜 二茂铁 电子传递
2010/8/24
合成了一种头基为二茂铁基团的长链烯烃分子(Fc-CO-NH-(CH2)9-CH=CH2) (FcUA)，并用红外、核磁、质谱等手段对其进行了表征。用微波引发将该化合物嫁接到平面硅的表面，并用X射线光电子能谱、反射红外光谱、原子力显微镜表征了这一过程。最后，通过循环伏安电化学法和电敏感原子力显微镜的导电模式对其进行电学性质测试。结果表明这层单分子膜可以提高硅片的介电常数。同时还观察到了一种不稳定的类...
