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 +10
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…
Couplings between Photons and Ensemble of Emitters in a High- Cavity at Mesoscopic Excitation Levels
Chenjiang Qian, Viviana Villafañe, Pedro Soubelet +2
We investigate the coupling between an ensemble of individual emitters and multiple photons in a high- cavity at the mesoscopic excitation level. The master equation theory is u…
Atomically Flat Dielectric Patterns for Band Gap Engineering and Lateral Junction Formation in MoSe Monolayers
Philipp Moser, Lukas M. Wolz, Alex Henning +9
Combining a precise sputter etching method with subsequent AlO growth within an atomic layer deposition chamber enables fabrication of atomically flat lateral patterns of SiO$_…
Polarons shape the interlayer exciton emission of MoSe/WSe heterobilayers
Pedro Soubelet, Alex Delhomme, Andreas V. Stier +1
We present time-resolved and CW optical spectroscopy studies of interlayer excitons (IXs) in 2 and 3stacked MoSe/WSe heterobilayers and obtain evidence for the stro…
Fast optoelectronic charge state conversion of silicon vacancies in diamond
Manuel Rieger, Viviana Villafane, Lina M. Todenhagen +5
Group IV vacancy color centers in diamond are promising spin-photon interfaces with strong potential for applications for photonic quantum technologies. Reliable methods for contro…
Transfer Matrix Model for Emission Profile Optimization of Radial Gratings
Stefan Appel, Viviana Villafane, Jonathan J. Finley +1
Radial Bragg gratings are commonly used to enhance light extraction from quantum emitters, but lack a well-suited, fast simulation method for optimization beyond periodic designs.…
Rapid spin depolarization in the layered 2D Ruddlesden Popper perovskite (BA)(MA)PbI
Michael Kempf, Philipp Moser, Maximilian Tomoscheit +8
We report temperature-dependent spectroscopy on the layered (n=4) two-dimensional (2D) Ruddlesden-Popper perovskite (BA)(MA)PbI. Helicity-resolved steady-state photoluminescence (P…
