英文摘要	an electrically bistable device has been fabricated using nanocomposite films consisting of silver nanoparticles and a semiconducting polymer by a simple spin-coating method. the current-voltage characteristics of the as-fabricated devices exhibit an obvious electrical bistability and negative differential resistance effect. the current ratio between the high-conducting state and low-conducting state can reach more than 103 at room temperature. the electrical bistability of the device is attributed to the electric-filed-induced charge transfer between the silver nanoparticles and the polymer, and the negative differential resistance behavior is related to the charge trapping in the silver nanoparticles. the results open up a simple approach to fabricate high quality electrically bistable devices by doping metal nanoparticles into polymer.; submitted by 阎军 (yanj@red.semi.ac.cn) on 2010-12-12t07:52:12z no. of bitstreams: 1 electrical bistability and negative differential resistance in diodes based on silver nanoparticle-poly(n-vinylcarbazole) composites.pdf: 1130619 bytes, checksum: 09ff2be18d92881262acfeab80816c05 (md5); approved for entry into archive by 阎军(yanj@red.semi.ac.cn) on 2010-12-12t08:06:47z (gmt) no. of bitstreams: 1 electrical bistability and negative differential resistance in diodes based on silver nanoparticle-poly(n-vinylcarbazole) composites.pdf: 1130619 bytes, checksum: 09ff2be18d92881262acfeab80816c05 (md5); made available in dspace on 2010-12-12t08:06:47z (gmt). no. of bitstreams: 1 electrical bistability and negative differential resistance in diodes based on silver nanoparticle-poly(n-vinylcarbazole) composites.pdf: 1130619 bytes, checksum: 09ff2be18d92881262acfeab80816c05 (md5) previous issue date: 2010; this work was partly supported by nsfc projects (grant nos. 60954001, 60825407, 60736034, and 50990064), "973" projects (grant no. 2010cb933800), program for ncet (grant no. 08-0717), key project of ministry of education (grant no. 109009), and the "111" project (grant no. b08002). the author (a. w. t.) is also grateful to china postdoctoral science foundation and the foundation from the key laboratory of luminescence and optical information (beijing jiaotong university), ministry of education.; 国内
