Multiferroicity and giant in-plane negative Poisson’s ratio in wurtzite monolayers

npj Computational Materials, 2022
Monolayers of layered materials, such as graphite and molybdenum dichalcogenides, have been the focus of materials science in the last decades. Here, we reveal benign stability and intriguing physical properties in the thinnest monolayer wurtzite (wz ...

On the mechanical properties and auxetic potential of various organic networked polymers [PDF]

, 2008
We simulate and analyse three types of two-dimensional networked polymers which have been predicted to exhibit on-axis auxetic behaviour (negative Poisson's ratio), namely (1) polyphenylacetylene networks that behave like flexing re-entrant honeycombs ...

Appearance of Supersonic Stoneley Waves in Auxetics

Crystals, 2022
It is shown that in auxetic materials (materials with negative Poisson’s ratio), supersonic Stoneley waves travelling without attenuation with a velocity equal to or exceeding maximum bulk wave velocity, may exist. Analytical expressions for the relation

Computational prediction of new auxetic materials

Nature Communications, 2017
There are very few inorganic materials with auxetic homogenous Poisson’s ratio in polycrystalline form. Here authors develop an approach to screening materials databases for target properties such as negative Poisson’s ratio by using stability and ...
