Weak Polar Optical Phonon Scattering Decouples Electron and Phonon Transport in Layered Thermoelectric Materials

By screening 236 layered semiconductors through high-throughput density functional theory calculations, this study identifies a strategy to decouple electron and phonon transport by mitigating polar optical phonon (POP) scattering, highlighting $\text{GaGe}_2\text{Te}$ as a high-performance thermoelectric candidate with high electrical conductivity and ultralow lattice thermal conductivity.

A Single Twist-Angle Selection Method for the Electronic Structure of Bilayer Materials

This paper introduces two new variants of the structure factor twist averaging (sfTA) method, "paired sfTA" and "binding sfTA," which improve the accuracy of calculating binding correlation energies in low-dimensional bilayer materials by incorporating binding interactions into the twist-angle selection process.

Room-temperature shape-memory effect in Sr(Ni $_{1-x}$ Cu $_x$ ) $_2$ P $_2$

The researchers demonstrate that substituting copper into $\text{SrNi}_2\text{P}_2$ allows for the tuning of structural transitions between uncollapsed, one-third collapsed, and fully collapsed states, enabling a large thermal hysteresis that can be adjusted to room temperature for potential use as a shape-memory material.

Spin excitation of the Heisenberg antiferromagnet with frustration: from the bounce-lattice antiferromagnet through the maple-leaf-lattice antiferromagnet to the exact-dimer system

This paper uses numerical diagonalization to investigate the spin excitation gaps of $S=1/2$ and $S=1$ Heisenberg antiferromagnets on various frustrated lattices, identifying specific transitions between gapped and gapless phases as the ratio of interaction strengths changes.

Interfacial breathing as a dynamic failure law in all-solid-state batteries: amplitude, phase lag and dual-timescale memory as design principles

This paper proposes a new dynamic failure law for all-solid-state batteries governed by two coupled processes—interfacial "breathing" (contact oscillations) and "reactive memory" (electrolyte decomposition)—and demonstrates that while stack pressure can suppress breathing, independent control of interphase chemistry is required to manage reactive memory.

Characterizing Fill Factor Limitations in Perovskite-Silicon Tandem Solar Cells

This paper presents a methodology to identify the primary causes of fill factor loss in perovskite-silicon tandem solar cells, specifically highlighting the impact of series resistance, the "photoshunt" phenomenon in perovskite layers, and the two-diode property of silicon cells.

Electron-phonon coupling across the TMD/hBN van der Waals interface

Using angle-resolved photoemission spectroscopy, the researchers demonstrate that quasiparticles in monolayer transition metal dichalcogenides (TMDs) are dressed by remote phonons from an adjacent hexagonal boron nitride (hBN) layer, revealing a generic interlayer electron-phonon coupling that could influence electron mobility and correlated phases in 2D heterostructures.
