- Abstract
- All-organic solution-processed two-terminal transistors were fabricated by replacing the "field-induced p-channel" of an organic field-effect transistor with a "photoinduced p-channel." A simple device structure-containing solution-processed 2,6-di(naphthalene-2-yl)-9,10-bis(triisopropylsilylethynyl)anthracene single crystals as the active layer (on a plastic substrate) and poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) as source and drain electrodes-enabled high-performance photosensor (and even transistor) behavior, showing pseudo-output and transfer curves with an on/off ratio of 5x10(2). We explain this photogenerated p-channel effect using Helfrich's theory, which describes the photodetrapping behavior of a space-charge-limited current under illumination.
