Development of two-dimensional titanium tin carbide (Ti2SnC) plates based on the electronic structure investigation

Titanium tin carbide (Ti2SnC) is a novel layered ternary compound. The ab initio calculations on the electronic structure and bonding properties indicated that Ti2SnC exhibit anisotropy of chemical bonding and properties. The electrical conductivity parallel to the basal plane is metallic and is much higher than that in c-axis. Thus Ti2SnC material in two-dimensional quasi-infinite form with the sheet surface parallel to the basal plane will show superior properties and have diverse device applications. Based on the theoretical predicted anisotropic electronic structure and properties, two-dimensional Ti2SnC plates were synthesized through a solid–liquid reaction process utilizing elemental Ti, Sn and C as starting materials. X-ray diffraction and scanning electron microscopy demonstrated that the morphology of the as-prepared plates were two-dimensional sheets. And the sheet surface was parallel to the (001) plane of Ti2SnC.
