Optical imaging of strain in two-dimensional crystals
Lukas Mennel, Marco M. Furchi, Stefan Wachter +3
Strain engineering is widely used in material science to tune the (opto-)electronic properties of materials and enhance the performance of devices. Two-dimensional atomic crystals…
Tunable and high purity room-temperature single photon emission from atomic defects in hexagonal boron nitride
Gabriele Grosso, Hyowon Moon, Benjamin Lienhard +7
Two-dimensional van der Waals materials have emerged as promising platforms for solid-state quantum information processing devices with unusual potential for heterogeneous assembly…
Mechanisms of photoconductivity in atomically thin MoS2
Marco M. Furchi, Dmitry K. Polyushkin, Andreas Pospischil +1
Atomically thin transition metal dichalcogenides have emerged as promising candidates for sensitive photodetection. Here, we report a photoconductivity study of biased mono- and bi…
Photovoltaic effect in an electrically tunable van der Waals heterojunction
Marco M. Furchi, Andreas Pospischil, Florian Libisch +2
Semiconductor heterostructures form the cornerstone of many electronic and optoelectronic devices and are traditionally fabricated using epitaxial growth techniques. More recently,…
Solar-energy conversion and light emission in an atomic monolayer p-n diode
Andreas Pospischil, Marco M. Furchi, Thomas Mueller
Two-dimensional (2D) atomic crystals, such as graphene and atomically thin transition metal dichalcogenides (TMDCs), are currently receiving a lot of attention. They are crystallin…
CMOS-compatible graphene photodetector covering all optical communication bands
Andreas Pospischil, Markus Humer, Marco M. Furchi +4
Optical interconnects are becoming attractive alternatives to electrical wiring in intra- and inter-chip communication links. Particularly, the integration with silicon complementa…
Microcavity-integrated graphene photodetector
Marco Furchi, Alexander Urich, Andreas Pospischil +8
The monolithic integration of novel nanomaterials with mature and established technologies has considerably widened the scope and potential of nanophotonics. For example, the integ…
