Controllable Spin-Polarized Transport in a Three-Terminal Model
《Communications in Theoretical Physics》2012年第6期1081-1086,共6页梁峰 杨永宏 汪军 
Supported by National Natural Science Foundation of China under Grant Nos. 10704016,110704032,110704033;Natural Science Foundation of Jiangsu Province under Grant No. BK2010416;National Basic Research Project of China under Grant No. 2009CB945504
By means of the Keldysh Green's function method,we investigate the spin-polarized electron transport in a three-terminal device,which is composed of three normal metal leads and two serially-coupled quantum dots(QDs)....

Magnetic Field Effects on Quantum-Dot Spin Valves
《Communications in Theoretical Physics》2009年第3期555-562,共8页GAO Jin-Hua SUN Qing-Feng XIE Xin-Cheng 
supported by the Chinese Academy of Sciences,US-DOE under Grant No.DE-FG02-04ER46124,US-Natural Science Foundation;National Natural Science Foundation of China under Grant Nos.10525418,10734110,and 60776060
We study the magnetic field effects on the spin-polarized transport of the quantum dot (QD) spin valve in the sequential tunneling regime. A set of generalized master equation is derived. Based on that, we discuss t...

Effective Mass of Strong-Coupling Bound Polaron in a Triangular Quantum Well Induced by Rashba Effect被引量:17
《Communications in Theoretical Physics》2008年第10期995-998,共4页ZHANG Hai-Rui XIAO Jing-Lin 
National Natural Science Foundation of China under Grant No.10347004
In this paper, on the basis of Huybrechts' strong-coupling polaron model, the Tokuda modified linearcombination operator method and the unitary transformation method are used to study the properties of the strongcoup...

Properties of a Bound Polaron under a Perpendicular Magnetic Field被引量:3
《Communications in Theoretical Physics》2007年第5X期930-934,共5页LIU Jia XIAO Jing-Lin HUO Shu-Fen CHEN Zi-Yui 
The project supported by National Natural Science Foundation of China under Grant No. 90305026
We investigate the influence of a perpendicular magnetic field on a bound polaron near the interface of a polar-polar semiconductor with Rashba effect. The external magnetic field strongly changes the ground state bin...

Zero-Magnetic-Field Spin Splitting of Polaron's Ground State Energy Induced by Rashba Spin-Orbit Interaction被引量:8
《Communications in Theoretical Physics》2006年第4X期761-765,共5页LIU Jia XIAO Jing-Ling 
The project supported by National Natural Science Foundation of China under Grant No. 10347004.
We study theoretically the ground state energy of a polaron near the interface of a polar-polar semiconductor by considering the Rashba spin-orbit (SO) coupling with the Lee-Low-Pines intermediate coupling method. O...
