Graphene transfer on TOPAS for flexible THz devices
We want to combine materials such as graphene with THz transparent polymers to develop new THz devices in this work. The project aims to optimize the graphene transfer on transparent polymer ( cyclic olefin copolymer - TOPAS).
Keywords: THz, graphene
The THz regime is the bridge between optics and electronics. Unfortunately, there is still a lack of ma-terials and devices in this area of the spectrum. We want to combine materials such as graphene with THz transparent polymers to develop new THz devices in this work. The project aims to optimize the graphene transfer on transparent polymer ( cyclic olefin copolymer - TOPAS). In addition, he/she will work on the haracterization of graphene with state-of-the-art equipment (figure 1 (a&b).
We are looking for motivated students with a background in physics, material science, electrical engi-neering, or chemistry for a master thesis in Transport at Nanoscale Interfaces Laboratory at Empa.
