The diamond and zinc-blende semiconductors are well-known and have been widely studied for decades. Yet, their electronic structure still surprises with unexpected topological properties of the valence bands. In this joint theoretical and experimental investigation we demonstrate for the benchmark compounds InSb and GaAs that the electronic structure features topological surface states below the Fermi energy. Our parity analysis shows that the spin-orbit split-off band near the valence band…

Topological crystalline insulators in the SnTe material class.

This work predicts the first material realization of topological crystalline insulator in the semiconductor SnTe by identifying its non-zero topological index and predicts that as a manifestation of this non-trivial topology, SnTe has metallic surface states with an even number of Dirac cones on high-symmetry crystal surfaces.

Topological crystalline insulators from crystal field effect in monolayer IV-VI semiconductors

Two-dimensional (2D) topological crystalline insulators (TCIs) were recently predicted in thin films of the SnTe class of IV-VI semiconductors, which can host metallic edge states protected by mirror

Crystal field effect induced topological crystalline insulators in monolayer IV-VI semiconductors.

It is demonstrated that (001) monolayers of rocksalt IV-VI semiconductors XY are 2D TCIs with the fundamental band gap as large as 260 meV in monolayer PbTe, and this crystal field effect induced topological phase offers a new strategy to find and design other atomically thin 2D topological materials.

Prediction of two-dimensional topological crystalline insulator in PbSe monolayer.

It is demonstrated that the PbSe nanostructure presents pairs of spin-polarized Dirac cones coming from the monolayer edges, where each Dirac pair presents a unique spin alignment, leading to a quantum spin Hall system.

Topological semimetal and Fermi-arc surface states in the electronic structure of pyrochlore iridates

We investigate novel phases that emerge from the interplay of electron correlations and strong spin-orbit interactions. We focus on describing the topological semimetal, a three-dimensional phase of

Observation of unusual topological surface states in half-Heusler compounds LnPtBi (Ln=Lu, Y)

This work directly observes the unusual topological surface states on rare-earth half-Heusler compounds LnPtBi, establishing them as first members with non-trivial topological electronic structure in this class of materials.

Observation of a topologically non-trivial surface state in half-Heusler PtLuSb (001) thin films

Spin- and angle-resolved photoemission spectroscopy reveals a surface state with linear dispersion and a helical tangential spin texture consistent with previous predictions, a significant step forward in establishing half-Heusler compounds as a viable material system for future spintronic devices.

Topological surface state of α -Sn on InSb(001) as studied by photoemission

We report on the electronic structure of the elemental topological semimetal alpha-Sn on InSb(001). High-resolution angle-resolved photoemission data allow us to observe the topological surface state

Topological quantum chemistry

A complete electronic band theory is proposed, which builds on the conventional band theory of electrons, highlighting the link between the topology and local chemical bonding and can be used to predict many more topological insulators.
