英文摘要	the ballistic transport of rashba electrons in a straight structure in two-dimensional electron gas is studied. it is found that there is no mixing between the wave functions of spin up and spin down states, and the transfer matrix is independent for the spin in every interface. the influence of the structure and rashba coefficient on the electron transport is investigated. our results indicate that the transmission probabilities are independent of the sign and magnitude of the rashba coefficient and it depends on the shape of the structure, especially the stub width. the antiresonance is found, where the quasiconfined state is formed in the center part of the structure.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-11-02t00:50:23z no. of bitstreams: 1 rashba electron’s ballistic transport in two-dimensional quantum waveguide.pdf: 258108 bytes, checksum: 15ffc21ca712ca90454e740102ed3e71 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-11-02t02:01:55z (gmt) no. of bitstreams: 1 rashba electron’s ballistic transport in two-dimensional quantum waveguide.pdf: 258108 bytes, checksum: 15ffc21ca712ca90454e740102ed3e71 (md5); made available in dspace on 2010-11-02t02:01:55z (gmt). no. of bitstreams: 1 rashba electron’s ballistic transport in two-dimensional quantum waveguide.pdf: 258108 bytes, checksum: 15ffc21ca712ca90454e740102ed3e71 (md5) previous issue date: 2010; 其它
