英文摘要	the beating patterns in the shubnikov-de haas oscillatory magnetoresistance originating from zero-field spin splitting of two-dimensional electron gases (2degs) in in0.52al0.48as/inxga1-xas/in0.52al0.48as quantum wells with silicon delta doped on the upper barrier layer have been investigated by means of magnetotransport measurements before and after illumination. contrary to the expectation, after each illumination, the beating nodes induced by the zero-field spin-splitting effect shift to lower and lower magnetic field due to the decrease in the zero-field spin-splitting energy of the 2degs. the anomalous phenomenon of the shift of the beating nodes and the decrease in spin-orbit coupling constants after illumination cannot be explained by utilizing the previous linear rashba model. it is suggested that the decrease in the zero-field spin-splitting energy and the spin-orbit coupling constant arise from the nonlinear rashba spin splitting.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-06-18t14:30:19z no. of bitstreams: 1 anomalous shift of the beating nodes in illumination-controlled in1-xgaxasin1-yalyas two-dimensional electron gases with strong spin-orbit interaction.pdf: 403931 bytes, checksum: dfe7a9dbd21fadbe46515772d19622eb (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-06-18t14:47:01z (gmt) no. of bitstreams: 1 anomalous shift of the beating nodes in illumination-controlled in1-xgaxasin1-yalyas two-dimensional electron gases with strong spin-orbit interaction.pdf: 403931 bytes, checksum: dfe7a9dbd21fadbe46515772d19622eb (md5); made available in dspace on 2010-06-18t14:47:01z (gmt). no. of bitstreams: 1 anomalous shift of the beating nodes in illumination-controlled in1-xgaxasin1-yalyas two-dimensional electron gases with strong spin-orbit interaction.pdf: 403931 bytes, checksum: dfe7a9dbd21fadbe46515772d19622eb (md5) previous issue date: 2010; this work was supported by the special funds for major state basic research project (grant no. 2007cb924900), the national natural science foundation of china (grants no. 60906045, no. 60221502, and no. 60606025), the national science foundation for post-doctoral scientists of china (grant no. 20070420634), and the scientific research foundation of guangxi university (grants no. x071109 and no. xb2090777).; 国内
