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…
Biaxial strain tuning of excitons in monolayer MoSe by high-temperature physical vapor deposition
S. Patel, T. Faltermeier, S. Puri +6
We present strain tuning of excitonic emission in monolayer MoSe by using a high-temperature physical vapor deposition (PVD). The use of two amorphous substrates, SiN$_{4…
Substrate interference and strain in the second harmonic generation from MoSe monolayers
S. Puri, S. Patel, J. L. Cabellos +4
Nonlinear optical materials of atomic thickness--such as non-centrosymmetric 2H transition metal dichalcogenide monolayers--have a second order nonlinear susceptibility (…
