英文摘要	we have demonstrated a two-color quantum well infrared photodetector (qwip) exhibiting simultaneous photoresponse with cutoff wavelengths at 11.8 and 14.5 mu m, respectively. strong photocurrent signals are observed at temperature of 77 k. the simultaneous two-color photoresponse is achieved by utilizing a simple design by broadening the width of the quantum well and selecting an appropriate doping density. the two peaks are attributed to the intersubband transitions from the ground state to the first excited state (bound state) and to the fifth excited state (continuum state), respectively.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-09-07t12:42:29z no. of bitstreams: 1 two-color quantum well infrared photodetector simultaneously working at 10-14 mu m.pdf: 675661 bytes, checksum: e3fe0457b229edb2dc39aa440930d55b (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-09-07t13:10:20z (gmt) no. of bitstreams: 1 two-color quantum well infrared photodetector simultaneously working at 10-14 mu m.pdf: 675661 bytes, checksum: e3fe0457b229edb2dc39aa440930d55b (md5); made available in dspace on 2010-09-07t13:10:20z (gmt). no. of bitstreams: 1 two-color quantum well infrared photodetector simultaneously working at 10-14 mu m.pdf: 675661 bytes, checksum: e3fe0457b229edb2dc39aa440930d55b (md5) previous issue date: 2010; 其它
