Strain engineering in van der Waals bilayers offers a route to nonlinear mechanical control at the THz regime. Here, the authors use ultralow-frequency Raman spectroscopy and first-principles calculations on 2 and 2 MoS bilayers to demonstrate that biaxial tensile strain contracts the interlayer van der Waals gap via a Poisson effect. This contraction hardens the interlayer breathing modes, driving the structure into a highly repulsive intermolecular regime characterized by a large Grüneisen parameter.
