High-responsivity graphene photodetectors integrated on silicon microring resonators
Simone Schuler, Jakob E. Muench, Alfonso Ruocco +9
Graphene integrated photonics provides several advantages over conventional Si photonics. Single layer graphene (SLG) enables fast, broadband, and energy-efficient electro-optic mo…
Single-Particle-Picture Breakdown in laterally weakly confining GaAs Quantum Dots
Daniel Huber, Barbara Ursula Lehner, Diana Csontosová +5
We present a detailed investigation of different excitonic states weakly confined in single GaAs/AlGaAs quantum dots obtained by the Al droplet-etching method. For our analysis we…
Device physics of van der Waals heterojunction solar cells
Marco M. Furchi, Florian Höller, Lukas Dobusch +3
Heterostructures based on atomically thin semiconductors are considered a promising emerging technology for the realization of ultrathin and ultralight photovoltaic solar cells on…
Graphene photodetector integrated on a photonic crystal defect waveguide
Simone Schuler, Daniel Schall, Daniel Neumaier +4
We present a graphene photodetector for telecom applications based on a silicon photonic crystal defect waveguide. The photonic structure is used to confine the propagating light i…
Thermal light emission from monolayer MoS2
Lukas Dobusch, Simone Schuler, Vasili Perebeinos +1
Because of their strong excitonic photoluminescence (PL) and electroluminescence (EL), together with an excellent electronic tunability, transition metal dichalcogenide (TMD) semic…
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…
