Topological insulators have been proposed to be best characterized as bulk magnetoelectric materials that show response functions quantized in terms of fundamental …
Abstract Trisodium bismuthide (Na3Bi) is the first experimentally verified topological Dirac semimetal, and is a 3D analogue of graphene hosting relativistic Dirac fermions. Its …
Understanding the effects of the interfacial modification to the functional properties of magnetic topological insulator thin films is crucial for developing novel technological …
Topology appears across condensed matter physics to describe a wide array of phenomena which could alter, augment, or fundamentally change the functionality of many technologies …

The naturally existing chalcogenide Bi2Se3 is topologically nontrivial due to the band inversion caused by the strong spin-orbit coupling inside the bulk of the material. The …
Bi2Se3, one of the most widely studied topological insulators (TIs), is naturally electron- doped due to n-type native defects. However, many years of efforts to achieve p-type Bi2Se3 …
In a topological insulator (TI), if its spin–orbit coupling (SOC) strength is gradually reduced, the TI eventually transforms into a trivial insulator beyond a critical point of SOC, at which …
We report the growth of high quality topological insulator Bi 2 Se 3 thin films on a single layer, transitional metal dichalcogenide MoS 2 film via van der Waals epitaxy in a planar …
Due to the increased surface to volume ratios, topological nanomaterials can enhance contributions from the topological surface states in transport measurements, which is critical …
