Numerical investigation of the Poisson's ratio of an amorphous bilayer 2D network material

This paper investigates the transverse contraction of amorphous bilayer 2D Silica with varying network heterogeneities under uniaxial tensile loading using athermal molecular simulations in LAMMPS. It turns out that increases nonlinearly x-strain while it decreases increasing heterogeneity. We show is possible to engineer heterogeneity materials, making them potential candidates for nano-electromechanical applications.
