英文摘要	the dark current characteristics and temperature dependence for quantum dot infrared photodetectors have been investigated by comparing the dark current activation energies between two samples with identical structure of the dots-in-well in nanoscale but different microscale n-i-n environments. a sequential coupling transport mechanism for the dark current between the nanoscale and the microscale processes is proposed. the dark current is determined by the additive mode of two activation energies: e-a,e-micro from the built-in potential in the microscale and e-a,e-nano related to the thermally assisted tunneling in nanoscale. the activation energies e-a,e-micro and e-a,e-nano decrease exponentially and linearly with increasing applied electric field, respectively.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-12-12t07:40:20z no. of bitstreams: 1 sequential coupling transport for the dark current of quantum dots-in-well infrared photodetectors.pdf: 355974 bytes, checksum: f86e06922a39595b51293933a4e487fb (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-12-12t08:06:23z (gmt) no. of bitstreams: 1 sequential coupling transport for the dark current of quantum dots-in-well infrared photodetectors.pdf: 355974 bytes, checksum: f86e06922a39595b51293933a4e487fb (md5); made available in dspace on 2010-12-12t08:06:23z (gmt). no. of bitstreams: 1 sequential coupling transport for the dark current of quantum dots-in-well infrared photodetectors.pdf: 355974 bytes, checksum: f86e06922a39595b51293933a4e487fb (md5) previous issue date: 2010; this work was financially supported by the national basic research program of china (grant no. 2006cb921507), national science foundation of china (grant nos. 10990100 and 60906058), and shanghai committee of science and technology (grant no. 08dz1400701).; 国内
