LOCAL-STRUCTURE OF THE AXIAL FE3+ CENTER IN THE K+ SITE OF A KTAO3 CRYSTAL

Physical Review B

In order to understand the unusually large value of zero-field splitting D for the axial Fe3+ center in a KTaO3 crystal, Zhou made two assumptions in his recent report [Phys. Rev. B 42, 917 (1990)]. In this Comment we will show that his assumption II is qualitatively r...

First-principle study of electronic properties of Ti3Si1-xAlxC2 solid solutions

Journal of Physics and Chemistry of Solids

The layered ternary ceramics Ti3SiC2 and Ti3AlC2 are isostructural and can form Ti3Si1-xAlxC2 solid solutions combining the advanced properties of both compounds [H.B. Zhang, Y.C. Zhou, Y.W. Bao, M.S. Li, Improving the oxidation resistance of Ti3SiC2 by forming a Ti3Si...

ZHOU Jiankun LIU Xianghuai CHEN Youshan WANG Xi ZHENG Zhihong HUANG Wei ZOU Shichang Shanghai Institute of Metallurgy , Academia Sinica , Shanghai , China

金属学报(英文版)

The TiN films were synthesized with an alternate process of depositing titanium from a E-gun evaporation source and 40 keV N~+ bombarding onto the target.It is shown from the composi- tion analysis and structure investigations using RBS,AES,TEM,XPS and X-ray diffraction spectrum that the formed fihn...

三维晶粒长大速率方程的大尺度Potts模型Monte Carlo仿真验证

王浩 , 刘国权 , 秦湘阁

采用Potts模型Monte Carlo方法对3种现存的三维个体晶粒长大速率拓扑依赖性 方程进行了仿真验证. 结果表明, Rivier速率方程认为晶粒 体积变化率dVf/dt与晶粒面数f成线性关系, 与仿真 结果明显不符, 不适用于描述三维晶粒长大过程的动力 学. 当晶粒面数f≥8时,
