Recently, the organic micro-nano single-crystal devices have attracted much attention,because they combine the advantages of single crystals and organic semiconductors, such asthe source of the organic micro-nano single crystal materials is wide, the researchers canalso change the structure of the organic molecules to adjust the performance of the devices,the organic micro-nano single crystals are not present grain boundary, the moleculararrangements is long range order, charge trap density was reduced to the minimum, etc. andovercome the difficulty in growing the large bulk crystals. However, based on bundles ordisorder of micro-nano single crystals on the growth substrate for fabricating devices,during the fabrication of the organic micro-nano single-crystal devices, the small sizesresult in the difficult operation of transferring the organic micro-nano single crystals fromthe growth substrate to the target substrate, leading to the low success ratio and timeconsumption and an organic micro-nano single crystal devices is only fabricated in theprocess. Hence, a highly effective method to fabricate the micro-nano single crystal devivesis requisite. It is desirable to directly grow the highly ordered and crystalline organicmicro-nano structure arrays on the substrate for micro-nano single crystal devives tofabricate. Because it can overcome the challenges of the low success ratio and the difficultoperation. Furthermore, a large number of micro-nano single crystal devices can besuccessfully fabricated in one step.In this paper, we have studyed the Copper Phthalocyanine and Derivatives materials,which is of good photoelectric property and stability. And a pushing transfer method hasbeen developed to align the organic micro-nano single crystal arrays. In this way a largenumber of micro-nano single crystal devives can be successfully fabricated in one stepwithout the difficult operation and low success ratio. The main results are as follows as:1. Using vapour transportation method, the CuPc and F16CuP micro-nano single crystalhave been obtained.2. A generally applicative method has been developed to form the organic micro-nanosingle crystal arrays. And using this method we have obtained the organic micro-nano singlecrystal arrays of F16CuPc and CuPc. Then a pushing transfer method has been analyzed indetail.3. Based on the organic micro-nano single crystal arrays, using the glass fibre as the maskto deposit the electrodes, a large number of the organic micro-nano single crystal field effecttransistors of CuPc and F16CuPc have been succesfully fabricated. a large number of CuPc micro-nano single crystal field effect transistors show good field-effect properties with highmobility (0.1cm2V-1s-1-0.725cm2V-1s-1) and low threshold voltage (-6-0V). In contrast to theproperties of CuPc, a large number of F16CuPc micro-nano single crystal field effecttransistors with high mobility(0.01-0.1cm2V-1s-1) and low threshold voltage (0-5V). Theresults show the promising potential for the large-number and high-efficiency fabrication ofthe organic micro-nano single crystal field effect transistors.
