Three-dimensional excitonic dipole anisotropy enables ultrabroadband polarization photodetection in CrCl3
Satyam Sahu, Jaganandha Panda, Martin Jindra +9
Simultaneous detection of the spectral and polarization properties of light is highly desirable for integrated imaging and photonic technologies but typically requires complex mult…
Interplay of Cl Substitution and He Irradiation in CrSBrCl
Satyam Sahu, Adeel Bukhari, Arijit Kayal +8
Two-dimensional magnetic semiconductors provide a promising platform for exploring the interplay between disorder, lattice dynamics, and resonant light--matter interactions. Among…
The Topography Trap: Sifting Interlayer Excitons from Strain-Related Artifacts in Real-World 2D Hetrostructures
Pablo Hernández López, Luka Pirker, Astrid Weston +8
Novel excitonic phenomena emerging in transition metal dichalcogenide (TMDC) heterostructures belong to the most exciting topics in contemporary physics of van der Waals materials.…
Robust phonon engineering and symmetry-selective lattice dynamics in CrSBrCl
Satyam Sahu, Arsalan Hashemi, Mahdi Ghorbani-Asl +9
Atomic substitution provides a controlled route to engineer lattice dynamics in low-symmetry two-dimensional materials. Here, by combining polarization-resolved Raman spectroscopy…
Resonance Raman Scattering and Anomalous Anti-Stokes Phenomena in CrSBr
Satyam Sahu, Charlotte Berrezueta-Palacios, Sabrina Juergensen +5
CrSBr, a van der Waals material, stands out as an air-stable magnetic semiconductor with appealing intrinsic properties such as crystalline anisotropy, quasi-1D electronic characte…
Strain-Induced Decoupling Drives Gold-Assisted Exfoliation of Large-Area Monolayer 2D Crystals
Jakob Ziewer, Abyay Ghosh, Michaela Hanušová +5
Gold assisted exfoliation (GAE) is a groundbreaking mechanical exfoliation technique, producing centimeter scale single crystal monolayers of 2D materials. Such large, high quality…
