Özet
The electric field-and charge transfer-induced topological properties of Sc2C(OH)(2) MXene layers are reported. The system transforms from a trivial insulator to a topological insulator and to a metal. The s-pd orbitals are exchanged during the topological phase transition. The modification of the bandgap along with the transition to the topological phase reveals that Sc2C(OH)(2) MXene is a multifunctional material. The nearly free states, which form ideal conduction channels, are responsible for the topological electronic band structures. Published by AIP Publishing.
