Development of two-dimensional titanium tin carbide (Ti_2SnC) plates based on the electronic structure investigation

摘要

Titanium tin carbide (Ti_2SnC) is a novel layered ternary compound. The ab initio calculations on the electronic structure and bonding properties indicated that Ti_2SnC 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 Ti_2SnC material in two-dimensional quasi-infinite Form with the sheet surface parallel to the basal plane will Show superior properties and have diverse device applica- Tions.
