Nanoscale Mapping of Strain-engineered Excitons in Monolayer WSe
Anna S. Roche, Nicholas V. Proscia, Paul D. Cunningham +12
Excitons in monolayer transition metal dichalcogenides (TMDs) are highly sensitive to external stimuli, allowing control of resonance energies and lifetimes through electric and ma…
Electrical Probing of Dark Excitons through Microwave Permittivity
Alex Stram, Zhida Liu, Ziheng Zhang +17
Excitons in atomically thin semiconductors are almost always probed through their optical signatures, because the short lifetimes of these transient quasiparticles are generally as…
Dimensional Control of Excitonic Interactions in Exfoliated 2D Molecular Crystals
Jonghyun Son, Seonghyun Koo, Daniel Yim +17
Excited states in molecular crystals depend on intermolecular coupling, charge-transfer interactions, dielectric screening and molecular packing. How reduced dimensionality modifie…
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…
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…
Self-Assembled hBN Wrinkles as Planar Optofluidic Channels
Xiliang Yang, Tetsuo Martynowicz, Allard Katan +3

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…
Nanosecond nanothermometry in an electron microscope
Florian Castioni, Yves Auad, Jean-Denis Blazit +8
Thermal transport in nanostructures plays a critical role in modern technologies. As devices shrink, techniques that can measure thermal properties at nanometer and nanosecond scal…
