Scalable Cyclic Olefin Copolymer Encapsulation for High Optical Quality of TMD Monolayers
Suprova Das, Md Tarik Hossain, Zlata Fedorova +8
Monolayer transition metal dichalcogenides (TMDs) combine a direct bandgap, strongly bound excitons, and pronounced second-order optical nonlinearity, which makes them promising ma…
Charge Tunable Optical Nonlinearity of Moiré Exciton-Polaritons
Zhijie Li, Kok Wee Song, Jens-Christian Drawer +16
Transition metal dichalcogenides represent a versatile platform to study strong light-matter interactions based on excitons and electrons in ordered lattices. Twist-engineering of…
Real-time probing of quadrupolar contributions to the absorption cross section of non-periodic systems
Anvar Khujakulov, Michele Guerrini, Carlo Andrea Rozzi +1
The non-perturbative evaluation of multipolar cross sections is essential for probing atomic and molecular responses to spatially inhomogeneous electric fields characteristic of na…
Kubo-Martin-Schwinger-Gated Imaginary-Time Reconstruction of Time-Resolved Electronic Circular Dichroism in Organic Excitonic Aggregates
Christian Tantardini, Caterina Cocchi
Time-resolved electronic circular dichroism (TR-ECD) and time-resolved circular dichroism (TRCD) probe chiral exciton dynamics prepared by an ultrafast pump and interrogated by a w…
Electronic localization and optical activity of strain-engineered transition-metal dichalcogenide nanobubbles
Stefan Velja, Alexander Steinhoff, Jannis Krumland +2
Strain-engineered transition-metal dichalcogenide nanobubbles are promising platforms for quantum emission, as revealed by recent experimental observations. In this work, we presen…
Janus MoSSe/WSSe Heterobilayers as Selective Photocatalysts for Water Splitting
Mostafa Torkashvand, Saeedeh Sarabadani Tafreshi, Caterina Cocchi +1
Identifying materials that simultaneously straddle the water redox potentials and possess an intrinsic electric field is crucial for achieving high solar-to-hydrogen (STH) efficien…
