- Abstract
- We fabricated cross-stacked organic p–n nanojunction arrays made of single-crystal 6,13-bis(triisopropylsilylethynyl) pentacene (TIPS-PEN) and fullerene (C60) nanowires as p-type and n-type semiconductors, respectively, by using a nanotransfer printing technique. Single-crystal C60 nanowires were synthesized inside nanoscale channels of a mold and directly transferred onto a desired position of a flexible substrate by a lubricant liquid layer. In the consecutive printing process, single-crystal TIPS-PEN nanowires were grown in the same way and then perpendicularly aligned and placed onto the C60 nanowire arrays, resulting in a cross-stacked single-crystal organic p–n nanojunction array. The cross-stacked single-crystal TIPS-PEN/C60 nanowire p–n nanojunction devices show rectifying behavior with on/off ratio of ∼13 as well as photodiode characteristic with photogain of ∼2 under a light intensity of 12.2 mW/cm2. Our study provides a facile, solution-processed approach to fabricate a large-area array of organic crystal nanojunction devices in a desired arrangement for future nanoscale electronics.
