ABSTRACT
The graphene-silicon junction is one of the simplest conceivable interfaces in graphene-integrated semiconductor technology that can lead to the development of future generation of electronic and optoelectronic devices. However, graphene's integration is currently expensive and time-consuming and shows several challenges in terms of large-scale device fabrication, effectively preventing the possibility of implementing this technology into industrial processes. Here, we show a simple and cost-effective fabrication technique, based on inkjet printing, for the realization of printed graphene-silicon rectifying devices. The printed graphene-silicon diodes show an ON/OFF ratio higher than 3 orders of magnitude and a significant photovoltaic effect, resulting in a fill factor of â¼40% and a photocurrent efficiency of â¼2%, making the devices suitable for both electronic and optoelectronic applications. Finally, we demonstrate large-area pixeled photodetectors and compatibility with back-end-of-line fabrication processes.
