Understanding inhomogeneous crystallization dynamics of phase-change materials in the vicinity of metallic nanoantennas
Luis Schüler, Lukas Conrads, Yingfan Chen +5
Optical metasurfaces composed of metallic or dielectric scatterers (meta-atoms) promise a powerful way of tailoring light-matter interactions. Phase-change materials (PCMs) are pri…
Fast Programming of In-Plane Hyperbolic Phonon Polariton Optics Through van der Waals Crystals using the Phase-Change Material In3SbTe2
Lina Jäckering, Umberto Saldarelli, Aaron Moos +8
The high directionality of hyperbolic phonon polaritons (HPhPs) has opened radically new ways to route and steer the flow of energy at the nanoscale. However, launching HPhPs requi…
Tailoring hBN's Phonon Polaritons with the Plasmonic Phase-Change Material In3SbTe2
Lina Jäckering, Aaron Moos, Lukas Conrads +8
Polaritons in van-der-Waals materials (vdWM) promise high confinement and multiple tailoring options by optical structures, e.g., resonators, launching structures and lenses. These…
Infrared Beam-shaping on Demand via Tailored Geometric Phase Metasurfaces employing the Plasmonic Phase-Change Material In3SbTe2
Lukas Conrads, Florian Bontke, Andreas Mathwieser +5
Conventional optical elements are bulky and limited to specific functionalities, contradicting the increasing demand of miniaturization and multi-functionalities. Optical metasurfa…
Super-resolution imaging of nanoscale inhomogeneities in hBN-covered and encapsulated few-layer graphene
Lina Jäckering, Konstantin G. Wirth, Lukas Conrads +9
Encapsulating few-layer graphene (FLG) in hexagonal boron nitride (hBN) can cause nanoscale inhomogeneities in the FLG, including changes in stacking domains and topographic defect…
Direct programming of confined Surface Phonon Polariton Resonators using the plasmonic Phase-Change Material InSbTe
Lukas Conrads, Luis Schüler, Konstantin G. Wirth +2
Tailoring light-matter interaction is essential to realize nanophotonic components. It can be achieved with surface phonon polaritons (SPhPs), an excitation of photons coupled with…
Hidden Schema Networks
Ramsés J. Sánchez, Lukas Conrads, Pascal Welke +2
Large, pretrained language models infer powerful representations that encode rich semantic and syntactic content, albeit implicitly. In this work we introduce a novel neural langua…
Experimental observation of ABCB stacked tetralayer graphene
Konstantin G. Wirth, Jonas B. Profe, Alexander Rothstein +10
In tetralayer graphene, three inequivalent layer stackings should exist, however, only rhombohedral (ABCA) and Bernal (ABAB) stacking have so far been observed. The three stacking…
