英文摘要	the second-harmonic generation (shg) from si1-xgex alloy films has been investigated by near-infrared femtosecond laser. recognized by s-out polarized shg intensity versus rotational angle of sample, the crystal symmetry of the fully strained si0.83ge0.17 alloy is found changed from the o-h to the c-2 point group due to the inhomogeneity of the strain. calibrated by double crystal x-ray diffraction, the strain-induced chi((2)) is estimated at 5.7 x 10(-7) esu. according to the analysis on p-in/s-out shg, the strain-relaxed si0.10ge0.90 alloy film is confirmed to be not fully relaxed, and the remaining strain is quantitatively determined to be around 0.1%.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-12-12t07:46:14z no. of bitstreams: 1 near-infrared femtosecond laser for studying the strain in si1-xgex alloy films via second-harmonic generation.pdf: 797213 bytes, checksum: 3a9976a19b083f7790acb30118f66979 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-12-12t08:06:36z (gmt) no. of bitstreams: 1 near-infrared femtosecond laser for studying the strain in si1-xgex alloy films via second-harmonic generation.pdf: 797213 bytes, checksum: 3a9976a19b083f7790acb30118f66979 (md5); made available in dspace on 2010-12-12t08:06:36z (gmt). no. of bitstreams: 1 near-infrared femtosecond laser for studying the strain in si1-xgex alloy films via second-harmonic generation.pdf: 797213 bytes, checksum: 3a9976a19b083f7790acb30118f66979 (md5) previous issue date: 2010; 国内
