Electronic Structure of Si1-xⅣx/Si Superlattices on Si （001）
《Chinese Physics Letters》2007年第3期811-813,共3页陈捷 吕铁羽 黄美纯 
Supported by the National Natural Science Foundation of China under Grant Nos 10274946 and 60336010.
We have preformed systematical ab initio studies of the structural and electronic properties of short-period Si1-xⅣx/Si （x = 0.125, 0.25, 0.5, Ⅳ=Ge, Sn） superlattices （SLs） grown along the [001] direction on bul...
ab initio CALCULATION FOR THE ELECTRONIC STRUCTURE OF GaAs/Al<sub>x</sub>Ga<sub>1-x</sub> As SUPERLATTICES: CONJUGATE GRADIENT APPROACH
《Transactions of Tianjin University》2001年第2期98-100,共页金英进 姜恩永 金光日 金成规 任世伟 
Supported by National Natural Science Foundation of China(No.50 0 72 0 1 5 and No.5980 1 0 0 6) and Tianjin Youth Foundation o
The electronic structure of GaAs/Al xGa 1-x As superlattices has been investigated by an ab initio calculation method—the conjugate gradient (CG) approach.In order to determine that,a conventional CG scheme is m...

Correlation between Thermal Expansion and Magnetic Characteristics of Fe-Ni Alloys in Fe_(1-x)Ni_x/Cu Superlattices
《International Journal of Minerals,Metallurgy and Materials》1998年第3期169-174,共6页Weizhong Tang H Zabel(Matrial Science and Engineering School, University of Science and Technology Beijing, Beijing 100083, China)(Institute of Experimental Physics/Solid State Physics, Ruhr University Bochum, 44780 Bochum, Germany) 
Thermal expansion behaviors of FeNi alloys were investigated by means of X-ray diffraction technique within a Fe1 -xNix/Cu superiattice structure. It was found that with a Ni concentration of x = 0.35, FeNi alloy laye...
