Graphene: A new material for electronics, Part 2

The first part of this blog series, Graphene: A new material for electronics, Part 1, describes the properties of the graphene material as a new substrate for next-generation integrated circuits. Graphene is showing a promising potential in many applications, such as light on a chip. Recently the researchers at the ICFO have published a work, that explains how nano-electromechanical systems, known as NEMS, can be combined with single-photon emitters, known as Nitrogen Vacancy Centers (NVCs), to create very innovative hybrid systems:

“Their work has confirmed that graphene is an ideal platform for both nanophotonics and nanomechanics. For their study, the researchers fabricated such an original hybrid device for the first time. Due to its electromechanical properties, graphene NEMS can be actuated and deflected electrostatically over few tens of nanometers with modest voltages applied to a gate electrode. The graphene motion can thus be used to modulate the light emission by the NVC, while the emitted field can be used as a universal probe of the graphene position. The optomechanical coupling between the graphene displacement and the NVC emission is based on near-field dipole-dipole interactions.” (Source: PHYS.org) (See Figure 1):

Graphene has an exceptional wide range of possible applications as a substrate for electronics ICs, this is demonstrated by the production of transparent OLED electrodes achieved recently by the Fraunhofer Institute as a result of a project, known as “GLADIATOR”, funded by the European Commission. (see Figure 2):

“Together with industrial partners, the Fraunhofer Institute for Organic Electronics, and Electron Beam and Plasma Technology FEP from Dresden have demonstrated the use of graphene in the production of transparent OLED electrodes. The research centre created an orange OLED with graphene electrodes measuring 20×10mm.” (Source: EEtimes Europe)
