Fast ultrahigh-density writing of low-conductivity patterns on semiconducting polymers


Organic thin films are used as active materials in optoelectronic devices, and especially in organic photovoltaic cells. The morphology of organic thin films has a strong influence on their practical device properties.  Farina et al. develop a patterning technique that is able to reduce polymer conductivity at nanoscales without leading to  morphological changes  and discuss its potential application in non-volatile data storage devices.
