Research, Development and characterization of a TunAble Graphene liGht Emitting hybrid MOEMS Device - TAGGED

Project summary

High performance solid-sate light sources are critical components in many MOEMS and have been the subject of much research in recent years. With the advent of graphene and thanks to its superior physical properties, a new field of research has been opened up for exploiting graphene properties for various applications. We aim to employ light emission properties of graphene when it is electrically biased, coupled with an electrostatically actuated substrate to develop a light source with tunable wavelength and intensity. A graphene layer is suspended over a substrate that can be positioned, allowing fine adjustment of its distance to the graphene layer, hence tuning the reflected light and its interferences with respect to wavelength and intensity. Such precisely engineered tunable light sources can provide a broad optical bandwidth and advance the spectral resolution in a variety of domains including spectroscopic measurements to investigate wavelength-dependent properties of materials.
