Electronic and Spin Structure of Topological Surface States in MnBi4Te7 and MnBi6Te10 and Their Modification by an Applied Electric Field

A. M. Shikin et al.

Summary: The electronic and spin structure of topological surface states in antiferromagnetic topological insulators MnBi4Te7 and MnBi6Te10 have been calculated, and the effects of different surface terminations on the properties have been analyzed. It is shown that the band gap at the Dirac point can be modulated by changing the layer distance and applying an electric field, which has potential applications.

Persistence of correlation-driven surface states in SmB6 under pressure

Soonbeom Seo et al.

Summary: This study investigates the evolution of the surface state of the proposed topological Kondo insulator SmB6 under hydrostatic pressure. The results show that the surface carrier density increases with increasing pressure, while the Fermi energy remains unchanged. The effective mass of the surface state charge carriers linearly increases with pressure, indicating the persistence of strong-correlation-driven surface states under pressure.

Slow crystalline electric field fluctuations in the Kondo lattice SmB6

M. Carlone et al.

Summary: This study reports on the temperature dependence of electron spin resonance (ESR) of Gd3+-doped SmB6 single crystals. An anomalous inhomogeneous broadening of the Gd3+ ESR linewidth was observed within a certain temperature range, which is attributed to slow crystalline electric field fluctuations. The observed properties are related to the structure and charge fluctuations of SmB6, providing important insights into its physical properties.

On the Percolation Regime of the Bulk Transport of the Bi1.08Sn0.02Sb0.9Te2S Topological Insulator

V Sakhin et al.

Summary: The formation of nanosized charge droplets in the bulk of a three-dimensional topological insulator Bi1.08Sn0.02Sb0.9Te2S was confirmed using electron spin resonance. The participation of electrons and holes in bulk conductivity is only possible through thermal activation or variable range hopping since they are locked in these droplets far apart from each other. Transport measurements showed that conduction follows the activation behavior at relatively high temperatures, with activation energies potentially much smaller than half of the forbidden band due to percolation. At sufficiently low temperatures, variable range hopping replaces activated transport.

Splitting of the Spectrum of Fermionic Excitations in a Topological Insulator by Charge Fluctuations

V. V. Val'kov

Summary: The Fermi excitation spectrum of a topological insulator has a four-band structure due to the splitting of the initial energy structure caused by the intersite Coulomb interaction. The dielectric gap is determined by the energy interval between the bottom of the band of fluctuation states of conduction electrons and the top of the valence band of fluctuation states, resulting in quasiparticles with different effective masses due to the narrow band of fluctuation states.

Systematic manipulation of the surface conductivity of SmB6

M. Victoria Ale Crivillero et al.

Summary: The resistivity plateau of SmB6 at low temperature can be influenced by different surface treatments, with focused ion beam treatment having a more pronounced effect. The temperature at which the resistance deviates from thermally activated behavior decreases with cumulative surface damage. This method provides a systematic way of controlling surface conductance.

Topological surface states on the nonpolar (110) and (111) surfaces of SmB6

Dong-Choon Ryu et al.

Summary: Researchers explored the surface states on the nonpolar (110) surface of SmB6 using ARPES experiment and DFT band calculations, identifying them as topological surface states of topological insulator nature and topological crystalline insulator nature. They also observed a Lifshitz transition of Fermi surfaces with intriguing spin textures in the double Dirac cones of the TCI nature by varying the chemical potential, and proposed a way to probe buried Dirac points on the nearly nonpolar (111) surface.
