Negative Poisson's Ratio

Stishovite exhibits a negative Poisson's ratio when stressed in a range of directions in the (100), (010) and (001) planes under specific ambient pressure ranges. This may be explained through mechanisms involving rotations and distortions of the constituent octahedral.

Size Of Particles

In this work we present results of Monte Carlo simulations of the elastic properties of Yukawa crystals with the polydispersity of size of particles. The results of our studies reveal an enhancement of negative Poisson's ratio (further referred to as auxeticity) due to size polydispersity in the system. We introduce a measure of auxeticity to estimate quantitatively an enhancement of auxetic properties which can be used to assess those changes in various systems.
