Pre-Patterned Superconducting Contacts for Clean Superconductor-Topological Material Interfaces Enabling Long-Range Josephson Coupling
Yong-Bin Choi, Chang-Won Choi, Luke Holtzman +8
Phase-coherent superconducting proximity in topological materials requires clean superconductor-topological material (SC-TM) interfaces, yet conventional top-contact fabrication of…
Self-Assembled hBN Wrinkles as Planar Optofluidic Channels
Xiliang Yang, Tetsuo Martynowicz, Allard Katan +3
Optically accessible, scalable planar nanofluidic channels are attractive for studying transport and localization under confinement. Two dimensional (2D) materials provide large ar…
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 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…
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…
