Strain-shear coupling in bilayer MoS2
Layered materials have strikingly anisotropic mechanical properties. Here, the authors use Raman spectroscopy and first-principles calculations to unveil that MoS2, an archetypal layered material, possesses a coupling between in-plane uniaxial strain and interlayer shear, enabling derivation of an u...

| Résumé: | Layered materials have strikingly anisotropic mechanical properties. Here, the authors use Raman spectroscopy and first-principles calculations to unveil that MoS2, an archetypal layered material, possesses a coupling between in-plane uniaxial strain and interlayer shear, enabling derivation of an unexplored off-diagonal elastic constant. |
