英文摘要	In this paper, a novel betavoltaic (BV) microcell based on semiconducting single-walled carbon nanotube (s-SWCNT) arrays/Si heterojunctions are demonstrated for the first time. The aligned arrays of p-type s-SWCNTs were prepared on n-type silicon to form the p-n heterojunctions as energy conversion by the traditional micro-fabrication process and dielectrophoretic (DEP) technology. The s-SWCNT arrays/Si p-n heterojunction displays better rectification characteristics than the SWCNT-based Schottky junctions such as Au/s-SWCNT/Ti and SWCNTs thin film/Si in our previous works. Under 7.8mCi/cm(2) Ni-63 irradiation, the open circuit voltage (V-OC) of 62mV, short current density (J(SC)) of 3.8 mu A/cm(2), fill factor (FF) of 33.4% and energy conversion efficiency (.) of 9.8% were achieved. The results indicated that this s-SWCNT arrays/Si microcell has a huge potential for application in BV microcells.; CPCI-S(ISTP); zhangjinwen@pku.edu.cn; 1102-1105
