Quick Fabrication of Large-area Organic Semiconductor Single Crystal Arrays with a Rapid Annealing Self-Solution-Shearing Method.

ABSTRACT: In this paper, we developed a new method to produce large-area single crystal arrays by using the organic semiconductor 9, 10-bis (phenylethynyl) anthracene (BPEA). This method involves an easy operation, is efficient, meets the demands of being low-cost and is independent of the substrate for large-area arrays fabrication. Based on these single crystal arrays, the organic field effect transistors exhibit the superior performance with the average mobility extracting from the saturation region of 0.2 cm(2) V(-1)s(-1) (the highest 0.47 cm(2) V(-1)s(-1)) and on/off ratio exceeding 10(5). In addition, our single crystal arrays also show a very high photoswitch performance with an on/off current ratio up to 4.1 × 10(5), which is one of the highest values reported for organic materials. It is be
