Engineering tunable strain fields in suspended graphene by microelectromechanical systems
Jens Sonntag, Matthias Goldsche, Tymofiy Khodkov +5
Here, we present a micro-electromechanical system (MEMS) for the investigation of the electromechanical coupling in graphene and potentially related 2D materials. Key innovations o…
Graphene-Quantum Dots Hybrid Photodetectors with Low Dark-Current Readout
D. De Fazio, B. Uzlu, I. Torre +10
Graphene-based photodetectors have shown responsivities up to 10A/W and photoconductive gains up to 10 electrons per photon. These photodetectors rely on a highly absorbi…
Tunable coupling of two mechanical resonators by a graphene membrane
G. J. Verbiest, M. Goldsche, J. Sonntag +4
Coupled nanomechanical resonators are interesting for both fundamental studies and practical applications as they offer rich and tunable oscillation dynamics. At present, the mecha…
Far-field Excitation of Single Graphene Plasmon Cavities with Ultra-compressed Mode-volumes
Itai Epstein, David Alcaraz, Zhiqin Huang +9
Acoustic-graphene-plasmons (AGPs) are highly confined electromagnetic modes, carrying large momentum and low loss in the mid-infrared/Terahertz spectra. Owing to their ability to c…
Detecting Ultrasound Vibrations by Graphene Resonators
G. J. Verbiest, J. N. Kirchhof, J. Sonntag +3
Ultrasound detection is one of the most important nondestructive subsurface characterization tools of materials, whose goal is to laterally resolve the subsurface structure with na…
