Higher-order phenomena in nanomechanics of two-dimensional material membranes

This thesis studies higher-order material properties* and effects in van der Waals crystals, such as anisotropic Young’s modulus, magnetostriction, and non-trivial thermal expansion effects near magnetic and electronic phase transitions, that can affect the nanomechanical motion ofmultilayer two-dimensional (2D) material membranes. These couplings make the motion of nanomechanical resonators a useful and universal tool to probe 2Dmaterial properties that are often hard to access otherwise. The thesis consists of four parts...
