Towards nanoprobes for conduction in molecular crystals: Dibenzoterrylene in anthracene crystals

The miniaturization of electronic devices and structures brings along the quest for instruments that operate on mesoscopic and nanometric scales. In these structures, nano-instruments could elucidate the rich variety of physical processes, an understanding of which will be necessary to develop and to predict the function of new nanoscale devices. For this purpose, we propose to use single molecules as nanoprobes and to address the probes individually by means of optical single molecule microscopy and spectroscopy. This would allow us to study the conduction in molecular crystals. Here, we compare different material systems and show that dibenzoterrylene in an anthracene crystal is a promising candidate system.
