Rutile-mimic 3D metamaterials with simultaneously negative Poisson's ratio and negative compressibility

Rutile-mimic 3D metamaterials with simultaneously negative Poisson's ratio and negative compressibility

The origin of negative Poisson's ratio in rutile-type oxides and fluorides is explored through density functional theory (DFT) simulation. The study highlights the dominant role of nearest-neighbor central force interactions, thereby inspiring the design of a new three-dimensional (3D) mechanic...
