Ultrafast Formation and Annihilation of Strongly Bound, Anisotropic Excitons
Lawson T. Lloyd, Tommaso Pincelli, Mohamed Amine Wahada +12
Van der Waals (vdW) layered materials with long-range magnetic order have the potential to enable novel optoelectronic and spintronic applications. Among these, CrSBr is an air-sta…
Electric-current control of anomalous Hall effect
Jianping Guo, Gusthavo M. S. Brizolla, Peng Rao +9
We demonstrate robust and reversible electric-current control of the anomalous Hall effect (AHE) in a two-dimensional WTe2/Fe3GeTe2 (FGT) stack. Applying a current through Td-WTe2…
Second-order Stark shifts exceeding 10GHz in electrically contacted SiV centers in diamond
Manuel Rieger, Nori N. Chavira Leal, Rubek Poudel +7
Negatively charged silicon vacancy centers (SiV) in diamond exhibit excellent spin coherence and optical properties, making them promising candidates for quantum technologies.…
Magnetic brightening of light-like excitons in a monolayer semiconductor
A. Delhomme, T. Amit, P. Ji +4
Monolayer transition-metal dichalcogenides, such as WSe, are direct gap, multi-valley semiconductors. Long-range electron-hole exchange interactions mix the valleys, yielding d…
Quantum sensing with spin defects in boron nitride nanotubes
Roberto Rizzato, Andrea Alberdi Hidalgo, Linyan Nie +4
Spin defects in semiconductors are widely investigated for various applications in quantum sensing. Conventional host materials such as diamond and hexagonal boron nitride (hBN) pr…
Robust trapping of 2D excitons in an engineered 1D potential from proximal ferroelectric domain walls
Pedro Soubelet, Yao Tong, Asier Astaburuaga Hernandez +4
We investigate the confinement of neutral excitons in a one-dimensional (1D) potential, engineered by proximizing hBN-encapsulated monolayer MoSe to ferroelectric domain walls…
