Figure (IMAGE) Science China Press Caption A chain-like two-dimensional material, few-layer alpha-Tellurium, has intrinsically geometric anisotropy, anisotropic inter-chain (-layer) vibrational behaviors, higher mobility along the non-covalent bonding direction and isotropic light absorption, as governed by the found covalent-like quasi-bonding for the inter-chain (-layer) interactions.
