All-Optical Control of Interfacial Polarization in MoS/WSe Heterobilayers
Muhammad Sufyan Ramzan, Giancarlo Soavi, Caterina Cocchi
All-optical tuning of van der Waals heterostructures with coherent radiation offers a promising path toward ultrafast memory and optoelectronic devices. In the first-principles fra…
Twist-angle Control of Nonlinear Interference in a ZnO Nanowire/Monolayer WSe Hybrid Structure
Maximilian Tomoscheit, Benedikt Mathes, Alexander Zaunick +6
Nanoscale devices that integrate materials of different dimensionalities (0D, 1D, and 2D) hold great potential for advanced applications in photonics and optoelectronics. A fundame…
Highly Efficient Exciton Modulation in MoSe/PdSe Heterostructures
Petr Rozhin, Emma Contin, Danae Katrisioti +15
Controlling exciton recombination in atomically thin semiconductors is central to their optoelectronic functionality, as the competition between radiative and non-radiative decay c…
Nonlinear Circular Dichroism Reveals the Local Berry Curvature
Nele Tornow, Paul Herrmann, Clemens Schneider +3
Light-matter interactions are governed by conservation laws of energy and momentum. For harmonic generation in crystalline solids, energy conservation imposes that incoming pho…
Valleytronics in 2D Materials Roadmap
Kyle L. Seyler, Giancarlo Soavi, Bent Weber +30
Valleytronics exploits non-equivalent energy extrema in the electronic band structure of crystalline solids -- the valley degree of freedom -- to encode, manipulate, and read out i…
Photoluminescence Quenching in WSe via p-Doping Induced by Functionalized Rylene Dyes
Ana M. Valencia, Theresa Kuechle, Maximiliam Tomoscheit +6
Hybrid heterostructures combining transition metal dichalcogenides (TMDs) with light-harvesting dyes are promising materials for next-generation optoelectronics. Yet, controlling a…
