Crystallizing electrons with artificially patterned lattices
Trevor G. Stanfill, Daniel N. Shanks, Michael R. Koehler +6
Wigner crystals are typically confined to ultralow temperatures where thermal motion is frozen out. Moiré superlattices in twisted two-dimensional materials have extended their st…

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…
