The effects of ion implantation on ployacetylene films PA have been studied with Ar~+, Fe~+, C1~+, I~+, Na~+ and K~+ ions in the energy range of 15—30 keV. The changes of PA films in the electrical conductivity, due to chemical doping and ion implantation in relation to their structure and depth profiles of impurities, were measured through infrared (ATR/FTIK), Rutherford backscattering spectrometry (RBS) and the four probe technique. In all cases, ion implantation of active ions exhibits the same effects as chemical doping. The formation of p-n junction is observed at the interface of implanted region and chemical doped PA substrate. The mechanism of interaction process between ion beam and polymer is also discussed. 相似文献

本文简要介绍了团簇冲击核聚变研究的发展和现状,同时也介绍了各种理论解释模型.A brief introduction of latest development of cluster impact fusion (CIF) was presented. Beuhler, Friedler and Friedman from BNL reported to have observed (d,d) fusion when deuterated solid target of TiD, (C2D). or ZrD1.65 were bombarded by (D,O): cluster with n values between 20 and 1000, accelerated to energies of 220~325 keV. The observed fusion rates correspond to cross sections some 25 ciders of magnitude larger than the theoretical estimation. A group in Stun fold Research Institute experimentally... 相似文献
