Journal ArticleDOI
Switching a Normal Insulator into a Topological Insulator via Electric Field with Application to Phosphorene
TL;DR: In this paper, the authors focus on the possibility of converting a normal insulator into a topological one by application of an external electric field that shifts different bands by different energies and induces a specific band inversion.
Journal ArticleDOI
Electric Field Induced Topological Phase Transition in Two-Dimensional Few-layer Black Phosphorus
TL;DR: This work predicts a continuous transition from the normal insulator to a topological insulator and eventually to a metal as a function of F⊥ on few-layer phosphorene, and opens the possibility of converting normal insulators into topological ones via electric field and making a multifunctional "field effect topological transistor" that could manipulate simultaneously both spin and charge carrier.
Journal ArticleDOI
Topological insulator Bi 2 Se 3 (111) surface doped with transition metals: An ab initio investigation
TL;DR: In this article, a map of the energetic stability and the electronic behavior of the topologically protected surface states of topological insulator (TI), Bi{}_{2}$Se${}_{3}$, doped with transition metals (TMs), was provided.

The enabling electronic motif for topological insulation in ABO3 perovskites and its structural stability
TL;DR: In this article, the authors identify the topological band inversion (TIB) of oxide topological insulators (TIs) and trace the basic design principles necessary to identify the window of opportunity of stable TIs.
Journal ArticleDOI
The Enabling Electronic Motif for Topological Insulation in ABO3 Perovskites
TL;DR: In this article, the authors trace the principles needed to design stable oxide topological insulators at ambient pressures as a) a search for oxides with small inversion energies; b) design of large inversion-energy oxide TIs that can be stabilized by pressure; and c) search for covalent oxides where TI-removing atomic displacements can be effectively screened out.
