unraveling Te-dominated transport in monolayer Sb 2 ...

Published on 2026-05-21 by Kai Wu, Ran Zhou, Hongliang Shi and Yifeng Duan @IOP SCIENCE

Abstract: Conventional Peierls theory is inadequate for describing thermal transport in strongly anharmonic compounds, such as two-dimensional layered chalcogenides containing lone-pair electrons; the underlying physics of their ultralow thermal conductivity remains to be explored. Here, using monolayer Sb Te as a model system, we elucidate the mechanism behind its ultralow lattice thermal conductivity by evaluating the competing contributions of particle-like propagation and wave-like tunneling. The part[...]


Our summary: This study investigates thermal transport in monolayer Sb2Te, revealing that quartic anharmonicity from lone-pair electrons suppresses particle-like transport. It also shows that wave-like transport is enhanced due to the flattening of phonon branches from weak covalent bonding. The combined model accurately predicts thermal conductivity, aligning well with experimental data.

Current density distribution for the quantum Hall effect

Published on 2026-05-15 by Serkan Sirt and Stefan Ludwig @IOP SCIENCE

Abstract: Our microscopic understanding of the integer quantum Hall effect is still incomplete. For decades, there has been a controversial discussion about ‘where the current flows’ if the Hall resistance is quantized. Here, we analyze the current density distribution in a Hall bar based on the screening properties of a two-dimensional electron system in the quantum Hall regime. Compared to previous publications, we consider the non-local nature of the quantum Hall effect and include a related persis[...]


Our summary: This study analyzes current density distribution in a Hall bar under the quantum Hall effect. It highlights the non-local nature of the effect and the presence of a persistent current. Results show that current flows in opposite directions along the edges of the Hall bar, influenced by Hall voltage and chemical potential.
