Topological phase diagrams of bulk and monolayer TiS2-x Tex.
With the use of ab initio calculations, the topological phase diagrams of bulk and monolayer TiS(2-x) Te(x) are established. Whereas bulk TiS(2-x) Te(x) shows two strong topological phases [1;(000)] and [1;(001)] for 0.44<x<0.56 and 0.56<x<1, respectively, the monolayer is topologically nontrivial for 0.48<x<0.80. Because in the latter doping range the topologically nontrivial nature survives d...
متن کاملPitfalls and feedback when constructing topological pressure- temperature phase diagrams
The stability hierarchy between different phases of a chemical compound can be accurately reproduced in a topological phase diagram. This type of phase diagrams may appear to be the result of simple extrapolations, however, experimental complications quickly increase in the case of crystalline trimorphism (and higher order polymorphism). To ensure the accurate positioning of stable phase domain...
متن کاملSpinodal Superlattices of Topological Insulators
Spinodal decomposition is proposed for stabilizing self-assembled interfaces between topological insulators (TIs) by combining layers of iso-structural and iso-valent TlBiX2 (X = S, Se, Te) materials. The composition range for gapless states is addressed concurrently to the study of thermodynamically driven boundaries. By tailoring composition, the TlBiS2−TlBiTe2 system might produce both spino...
متن کاملTopological features and gauge fields in graphene superlattices. Detecting Topological Currents in Graphene Superlattices
The quest for crystals whose electronic bands show non trivial topological features has not ceased since the discovery of the Quantum Hall Effect. The amazing current quantization in QHE devices can be traced back to edge states which emerge from non trivial electronic structures[1, 2]. Topological properties are typically associated to integer numbers, so that they are quite robust against per...
متن کاملDetecting topological currents in graphene superlattices.
Topological materials may exhibit Hall-like currents flowing transversely to the applied electric field even in the absence of a magnetic field. In graphene superlattices, which have broken inversion symmetry, topological currents originating from graphene's two valleys are predicted to flow in opposite directions and combine to produce long-range charge neutral flow. We observed this effect as...
