Nonlinear Anisotropy in Phase-Tuned Wide-Gap Halides
L. Landivar Scott, L. M. Vogl, C. Klenke +2
Silver iodide (AgI) thin films offer a compelling platform for studying nonlinear optical phenomena due to their intrinsic noncentrosymmetric lattice and direct band gap. Here, we…

Tuning Terahertz Optomechanics of MoS2 Bilayers with Homogeneous In-plane Strain
S. Patel, Jose D. Mella, S. Puri +2
Homogeneous in-plane biaxial tensile strain strengthens the out-of-plane van der Waals (vdW) interaction in \MoS\ bilayers (BLs) and can be used to fine-tune their terahertz (THz)…

Deformation-Potential-Driven Photostriction in Layered Ferroelectrics
S. Puri, R. Rodriguez, C. Dansou +5
The coupling between electronic excitations and lattice deformation in van der Waals ferroelectrics is governed by a competition between the electron deformation potential and the…
