Motivated by the synthesized Cu 4 Ti Se 4 with ultralow room-temperature thermal
conductivity [Angew. Chem., Int. Ed. 60, 9106 (2021)], we systematically investigate its …

Topological phononics, a fascinating frontier in condensed matter physics, holds great
promise for advancing energy‐related applications. Topologically nontrivial phonons …

Half semiconductors, capable of achieving 100% spin-polarized carriers under simple
electrostatic gating, optical excitation, and thermal excitation conditions, have emerged as …

We propose an ab initio Boltzmann transport approach taking into account magnon-phonon
scattering (MPS) and three-phonon scattering simultaneously to accurately evaluate the …

Phonons are an ideal platform for realizing stable spinless two-dimensional (2D) Dirac
points because they have a bosonic nature and hard-to-break time-reversal symmetry. It …

Effective regulation of phonon thermal conductivity is crucial for the understanding of
phonon transmission and improving thermoelectric (TE) performance. Using density …

We present an atomistic simulation of thermoelectric properties in cove-edged graphene
nanoribbons (CGNRs) via the nonequilibrium Greenes function. Different from gapless …

Due to their high electromechanical coupling and energy density properties, ultrathin
piezoelectric films have recently been intensively studied as key materials for the …

Acoustic phonons have long been believed to dominate the lattice thermal conductivity (κ l)
and the contribution of optical phonons can be neglected in crystal structures. KCaBi, as a …

Topological phases of matter, originally derived from condensed matter physics, have been
extensively exploited in photonics and phononics, and recently in mechanical metamaterial …
