Italian researchers develop a graphene-based OFET for future OLED and OLET displays

Researchers from Italy's ISOF-CNR, University of Naples "Federico II" and Università di Modena e Reggio Emilia have developed new organic n-type FET transistors (OFETs) based on CVD graphene sheets. The researchers say that the new process and materials they used can enable flexible, transparent and short-channel OFETs - which could be used in the future for OLED or OLET (organic light emitting transistor) displays.

To create the new transistors, the researchers used thermally evaporated thin-films of PDIF-CN2 (a perylene diimide derivative) as the the organic semiconductor for the active channel of the transistor with the single-layer CVD graphene (grown at Italy's IIT institute) as the electrode material. The final device architectures have been fabricated via Electron-Beam-Lithography (EBL) and Reactive Ion Etching (RIE).

Displays consume the most power in electronic gadgets. Portable devices like smartphones and VR visors therefore require most of the energy from batteries. As an alternative solution, reflective-type displays (like those in e-book readers) consume much less power, though they cannot deliver video. Reflective displays that offer the specifications of standard technologies (OLED, LCD) do not exist yet, but graphene may open the door to such possibilities.
