Thermodynamic reciprocity in scanning photocurrent maps
Mark B. Lundeberg, Frank H. L. Koppens
Scanning photocurrent maps in inhomogeneous materials contain nontrivial patterns, which often can only be understood with a full model of device geometry and nonuniformities. We r…
Dissociation of two-dimensional excitons in monolayer WSe2
Mathieu Massicotte, Fabien Vialla, Peter Schmidt +11
Two-dimensional (2D) semiconducting materials are promising building blocks for optoelectronic applications, many of which require efficient dissociation of excitons into free elec…
Probing the Ultimate Plasmon Confinement Limits with a Van der Waals heterostructure
David Alcaraz Iranzo, Sebastien Nanot, Eduardo J. C. Dias +11
The ability to confine light into tiny spatial dimensions is important for applications such as microscopy, sensing and nanoscale lasers. While plasmons offer an appealing avenue t…
Tuning quantum non-local effects in graphene plasmonics
Mark Lundeberg, Yuanda Gao, Reza Asgari +11
The response of an electron system to electromagnetic fields with sharp spatial variations is strongly dependent on quantum electronic properties, even in ambient conditions, but d…
Out-of-plane heat transfer in van der Waals stacks: electron-hyperbolic phonon coupling
K. J. Tielrooij, N. C. H. Hesp, A. Principi +20
Van der Waals heterostructures have emerged as promising building blocks that offer access to new physics, novel device functionalities, and superior electrical and optoelectronic…
Super-Planckian electron cooling in a van der Waals stack
Alessandro Principi, Mark B. Lundeberg, Niels C. H. Hesp +3
Radiative heat transfer (RHT) between macroscopic bodies at separations that are much smaller than the thermal wavelength is ruled by evanescent electromagnetic modes and can be or…
