Inelastic Scattering of Electron Beams by Nonreciprocal Nanotructures
Renwen Yu, Andrea Konečná, F. Javier García de Abajo
Probing optical excitations with high resolution is important for understanding their dynamics and controlling their interaction with other photonic elements. This can be done usin…
Ultrafast Topological Engineering in Metamaterials
Renwen Yu, Rasoul Alaee, Robert W. Boyd +1
Transient optical heating provides an efficient way to trigger phase transitions in naturally occurring media through ultrashort laser pulse irradiation. A similar approach could b…
Tracking ultrafast hot-electron diffusion in space and time by ultrafast thermo-modulation microscopy
Alexander Block, Matz Liebel, Renwen Yu +4
The ultrafast response of metals to light is governed by intriguing non-equilibrium dynamics involving the interplay of excited electrons and phonons. The coupling between them giv…
Tunable plasmons in ultrathin metal films
Rinu Abraham Maniyara, Daniel Rodrigo, Renwen Yu +7
The physics of electrons, photons, and their plasmonic interactions changes greatly when one or more dimensions are reduced down to the nanometer scale. For example, graphene shows…
Photothermal Engineering of Graphene Plasmons
Renwen Yu, Qiushi Guo, Fengnian Xia +1
Nanoscale photothermal sources find important applications in theranostics, imaging, and catalysis. In this context, graphene offers a unique suite of optical, electrical, and ther…
Efficient Electrical Detection of Mid-Infrared Graphene Plasmons at Room Temperature
Qiushi Guo, Renwen Yu, Cheng Li +4
Optical excitation and subsequent decay of graphene plasmons can produce a significant increase in charge-carrier temperature. An efficient method to convert this temperature eleva…
