Observation of magnetically switchable quantum geometric photocurrents
Qi Tian, Zhuoliang Ni, Matthew Cothrine +6
In non-centrosymmetric materials, light can be rectified into two types of DC photocurrents, known as injection and shift currents, through the bulk photovoltaic effect. Recent the…
Correlation-Driven Spin Reorientation via Competing Anisotropy Channels in CrPS4
Raju Baral, Harald O. Jeschke, Igor I. Mazin +3
We identify a correlation-driven mechanism for the temperature-induced spin reorientation in the quasi-one-dimensional van der Waals antiferromagnet CrPS4. Magnetic pair distributi…
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…
Strain-induced multiferroicity in Cr1/3NbS2
Y. Sun, Y. Ahn, D. Sapkota +7
Multiferroic materials, in which electric polarization and magnetic order coexist and couple, offer rich opportunities for both fundamental discovery and technology. However, multi…
Dynamic Interfacial Quantum Dipoles in Charge Transfer Heterostructures
Ziyu Liu, Emil Viñas Boström, Dihao Sun +7
Hysteretic gate responses of two-dimensional material heterostructures serve as sensitive probes of the underlying electronic states and hold significant promise for the developmen…
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…
