Research, development and characterization of a tunable light-emitting graphene-MOEMS device - TAGGED

The goal of this project is to exploit the visible and mid-infrared (thermal) light emission properties of graphene when electrically biased in conjunction with an electrostatically actuated substrate and develop a light source with tunable wavelength and intensity. In this concept, a thin free-standing graphene layer is suspended above a substrate (a beam or membrane) that can be electrostatically positioned so that its distance from the graphene layer can be finely tuned, allowing the reflected light and its interference effects to be tuned in terms of its wavelength and intensity. Such precisely designed tunable light sources can provide a wide optical bandwidth and thus improve spectral resolution in a variety of areas, including spectroscopic measurements to study wavelength-dependent material properties.
