Freeform nanostructuring of hexagonal boron nitride
Nolan Lassaline, Deepankur Thureja, Thibault Chervy +4
Hexagonal boron nitride (hBN)-long-known as a thermally stable ceramic-is now available as atomically smooth, single-crystalline flakes, revolutionizing its use in optoelectronics.…
Tunable quantum confinement of neutral excitons using electric fields and exciton-charge interactions
Deepankur Thureja, Atac Imamoglu, Tomasz Smolenski +10
Quantum confinement is the discretization of energy when motion of particles is restricted to length scales smaller than their de Broglie wavelength. The experimental realization o…
Reconsidering the design of planar plasmonic lasers: gain, gap layers, and mode competition
Marianne Aellen, Aurelio A. Rossinelli, Robert C. Keitel +4
Because surface plasmons can be confined below the diffraction limit, metallic lasers that support plasmonic modes can provide miniaturized sources of electromagnetic waves. Such d…
Phase Transitions in Germanium Telluride Nanoparticle Phase-Change Materials Studied by Time-Resolved X-Ray Diffraction
Ann-Katrin U. Michel, Felix Donat, Aurelia Siegfried +6
Germanium telluride (GeTe), a phase-change material, is known to exhibit four different structural phases: three at room temperature (one amorphous and two crystalline, and …
The Potential of Combining Thermal Scanning Probes and Phase-Change Materials for Tunable Metasurfaces
Ann-Katrin U. Michel, Sebastian Meyer, Nicolas Essing +5
Metasurfaces allow for the spatiotemporal variation of amplitude, phase, and polarization of optical wavefronts. Implementation of active tunability of metasurfaces promises compac…
Spectrally-resolved dielectric function of amorphous and crystalline GeTe nanoparticle thin films
Ann-Katrin U. Michel, Marilyne Sousa, Maksym Yarema +5
Phase-change materials (PCMs), which are well-established in optical and random-access memories, are increasingly studied for emerging topics such as brain-inspired computing and a…
