Graphene photodetectors with a bandwidth larger than 76 GHz fabricated in a 6 inch wafer process line
Daniel Schall, Caroline Porschatis, Martin Otto +1
In recent years, the data traffic has grown exponentially and the forecasts indicate a huge market that could be addressed by communication infrastructure and service providers. Ho…
Controlled generation of a pn-junction in a waveguide integrated graphene photodetector
Simone Schuler, Daniel Schall, Daniel Neumaier +5
With its electrically tunable light absorption and ultrafast photoresponse, graphene is a promising candidate for high-speed chip-integrated photonics. The generation mechanisms of…
Experimental verification of electro-refractive phase modulation in graphene
Muhammad Mohsin, Daniel Neumaier, Daniel Schall +5
Graphene has been considered as a promising material for opto-electronic devices, because of its tunable and wideband optical properties. In this work, we demonstrate electro-refra…
Electrical observation of a tunable band gap in bilayer graphene nanoribbons at room temperature
Bartholomaeus N. Szafranek, Daniel Schall, Martin Otto +2
We investigate the transport properties of double-gated bilayer graphene nanoribbons at room temperature. The devices were fabricated using conventional CMOS-compatible processes.…
Electrical transport and low-temperature scanning tunneling microscopy of microsoldered graphene
V. Geringer, D. Subramaniam, A. K. Michel +7
Using the recently developed technique of microsoldering, we perform a systematic transport study of the influence of PMMA on graphene flakes revealing a doping effect of up to 3.8…
