constant is greatly enhanced. These effects may be attributed to the substitution actions of the rare earth element in perovskite lattice. At the doping content of 0.75%, the dielectric constant maximum......
掺磷四面体非晶碳薄膜的电学性能刘爱萍1,2,朱嘉琦2,唐为华0,李超荣2(1.浙江省杭州市浙江理工大学先进纺织材料与制备技术教育部重点实验室2.黑龙江省哈尔滨市哈尔滨工业大学复合材料研究所)摘 要:采用过滤阴极真空电弧技术以PH3为掺杂源,施加0-200 V基底负偏压,制备了掺磷四面体非晶碳(ta-C:P)薄膜,利用X射线光电子能谱(XPS)和Raman光谱研究ta-C:P薄膜的微观结构,通过测定变温电导率和电流-电压曲线,考察ta-C:P薄膜的导电行为.结果表明,磷掺入增加了薄膜中sp2杂化碳原子含量和定域电......
was also investigated. Either doping the anatase TiO2 or adding the surface active agent or both of them can widen sintering temperature range which satisfies the zero temperature coefficient (0±30... containing bismuth with composition corresponding to (Bi3xZn2-3x)(ZnxNb2-x)O7 system. The effects of adding the surface active agent and the effects of anatase TiO2 doping on the phase composition......
density. Intermediate annealings result in notable decreasing resistivity due to the precipitation of the iron atoms from the Cu matrix and decrease of solute scattering resistivity. The doping with Zr...), while the strength of deformation-processed Cu-11.5%Fe in-situ composite is the lowest. It also shows that the doping with alloy elements Zr improves the strength of in-situ composite with a little......

. The results indicate that doping Ag greatly improves the photocatalytic efficiency of ZnO and 3% Ag-doped (mole fraction) ZnO porous microrod photocatalyst exhibits the highest photocatalytic... doped with various transition metal dopants has been investigated in detail [11-15]. In fact, doping metals except for Ag has shown the intangible (positive and negative) impact because......
