In-Substrate Imaging of Diamond hBN FET Current via Widefield Quantum Diamond Microscopy
Anuj Bathla, Subrat Kumar Pradhan, Ajit Kumar Dash +7
We demonstrate widefield magnetic imaging of current flow in hydrogen terminated diamond field effect transistors (FETs) through in-substrate nitrogen vacancy (NV) centers. Hydroge…
Real-Space Imaging of Moiré-Confined Excitons in Twisted Bilayer MoS
Laurens J. M. Westenberg, Lumen Eek, Jort D. Verbakel +8
Twisted two-dimensional semiconductors generate a moiré landscape that confines excitons (bound electron-hole pairs) into programmable lattices, offering routes to efficient light…
Probing the Nanoscale Excitonic Landscape and Quantum Confinement of Excitons in Gated Monolayer Semiconductors
Yueh-Chun Wu, Bogdan Dryzhakov, Huan Zhao +6
Engineering and probing excitonic properties at the nanoscale remains a central challenge in quantum photonics and optoelectronics. While exciton confinement via electrical control…
3D microwave imaging of a van der Waals heterostructure
Leonard W. Cao, Chen Wu, Lingyuan Lyu +9
Van der Waals (vdW) heterostructures offer a tunable platform for the realization of emergent phenomena in layered electron systems. While scanning probe microscopy techniques have…
Probing Vortex Dynamics in 2D Superconductors with Scanning Quantum Microscope
Sreehari Jayaram, Malik Lenger, Dong Zhao +9
The visualization of the magnetic responses of a two-dimensional (2D) superconducting material on the nanoscale is a powerful approach to unravel the underlying supercurrent behavi…
Cryogenic Nano-Imaging of Excitons in a Monolayer Semiconductor
Anna Roche, Michael R. Koehler, David G. Mandrus +4
Excitons, Coulomb bound electron-hole pairs, dominate the optical response of two-dimensional semiconductors across near-infrared and visible frequencies due to their large binding…
