英文摘要： Under the financial support from the National Natural Science Foundation of China, the electrical and mechanical properties of micro/nano structures were studied as follow: 1) The flexibility and the Young's modulus of the CuPc single crystal nanowires are studied, and the field-effect mobility of the CuPc nanowires at the bent and straight states were studied with the statistic method. It was found that the bent CuPc nanowire represents a 50% increase in mobility compared with that of the straight wire, which is in good agreement with the previous theoretical studies. These results have been published on "small" as the cover paper. 2) Organic nanowire circuits with inorganic nanowire electrodes have been fabricated and the related results have been published on Advanced Materials as cover paper, which was addressed as "an alternative to silicon in computer chips". 3) The high-performance CuPc field-effect transistor has been realized by a size controllable graphene micro/nanogap fabrication method using micro/nanowire. 4) P-N junction based on CuPc and F16CuPc nanowires have been fabricated and its field effect properties and optical-voltage properties have been studied. 5) Controlled growth of oriented organic nanowire arrays for the controllable device fabrication has been realized by pulling method. 6) Nanowire transistor with the ultralow work voltage has been realized. 7) The growth of the organic single crystal wires for potential application in electronic and optoelectronics has been studied. We have achieved all the targets in the plan. Based on these studies, seven papers have been published, such as small (1), Adv. Mater. (1), J. Am. Chem. Soc. (1) et al, and the total impact factor are high up to about 40.?Organized 2011 China-Denmark International Conference on Nanoelectronics (5rd)
