RESUMO
We demonstrate inkjet printing as a viable method for large-area fabrication of graphene devices. We produce a graphene-based ink by liquid phase exfoliation of graphite in N-methylpyrrolidone. We use it to print thin-film transistors, with mobilities up to â¼95 cm(2) V(-1) s(-1), as well as transparent and conductive patterns, with â¼80% transmittance and â¼30 kΩ/â¡ sheet resistance. This paves the way to all-printed, flexible, and transparent graphene devices on arbitrary substrates.
