	Manufacturing and testing of the line-array fiber-optic image slicer based on silicon V-grooves (EI CONFERENCE) 会议论文 OAI收割 MEMS/MOEMS Technologies and Applications III, November 12, 2007 - November 14, 2007, Beijing, China 作者: Zhu Y. 收藏 \| 浏览/下载：23/0 \| 提交时间：2013/03/25 Linear fiber-optic image slicer is used more and more in spatial exploration and imaging system. In this paper a plane arranging method of fiber-optic array based on Si-V grooves is established in order to improve the accuracy and reduce the cost of manufacturing. Firstly the Si-V groove array is micro-machined with anisotropic etching process then optical fibers are placed in the grooves orderly with plane arranging method. Secondly the end surfaces of the device are polished also the linear fiber-optic image slicer is packaged. Finally some parameters are tested including structure parameters transmittivity and vibration test. Experimental results indicate that the maximum error accumulated in 2000 periods of the Si-V grooves is 0.5 m the error of the height in Si-V grooves is less than 0.15m the roughness of the end surface is less than 0.9nm. The transmittivity of the linear fiber-optic image slicer that without optical film is 51.46% at the wavelength of 632.8nm. After random vibration experiment the ratio of the broken fiber increased by 0.1%. While the temperature reached 320C the stress of epoxy will be 130Mpa which is close to the limit resistance stress of 139Mpa some cracks appeared.
	Formation and characteristics of quantum dots of wide band gap II-VI semiconductor (EI CONFERENCE) 会议论文 OAI收割 Fifth International Conference on Thin Film Physics and Applications, May 31, 2004 - June 2, 2004, Shanghai, China Fan X. W.; Shan C. X.; Yang Y.; Zhang J. Y.; Liu Y. C.; Lu Y. M.; Shen D. Z. 收藏 \| 浏览/下载：28/0 \| 提交时间：2013/03/25 CdSe and ZnCdSe quantum dots (QDs) were grown under Stranski-Krastanow (S-K) mode by low-pressure metalorganic chemical vapor deposition (LP-MOCVD). The formation process of CdSe QDs below critical thickness was observed by atomic force microscopy (AFM). The formation mechanism of CdSe QDs below the critical thickness was due to the effect of surface diffusion and strain release. ZnCdSe QDs were grown based on the calculated critical thickness. Two kinds of variations in the ZnCdSe QDs appeared over time the Ostwald ripening process and dot formation process. ZnSeS dots were grown under Volmer-Weber (V-W) mode. With increasing the growth duration the size of dots becomes larger and the density decreases which is explained by virtue of the surface free energy.
