Chiral Acoustic Phonon and Conservation of Pseudoangular Momentum in α‐Quartz
Chiral acoustic phonons in α‐quartz are probed via Brillouin light scattering, exploiting the photon's helicity and the crystal's handedness. The interaction obeys a selection rule arising from pseudoangular momentum conservation, enabling direct optical access to phonon chirality in nonsymmorphic crystals.

Microscopic Theory of Spin Seebeck Effect in Antiferromagnets
We develop a microscopic theory for the spin Seebeck effect (SSE) in Néel and canted phases of antiferromagnetic insulators. We calculate the DC spin current tunneling from the antiferromagnet to an attached metal, incorporating the spin-wave theory and the non-equilibrium Green's function approach. Our result shows a sign change of the spin current at

Toward a Consensus Characterization Protocol for Organic Thermoelectrics
We advocate a common consensus on accurate and standardized reporting of performance metrics in the field of organic thermoelectrics. We summarize prevalent issues in the literature and propose a pre‐submission checklist to support the publication of reproducible results.

Magnesium silicide (Mg2Si) is introduced as a narrow‐bandgap, biodegradable semiconductor for transient electronics. RF‐sputtered and annealed Mg2Si thin films show high intrinsic electrical conductivity and low thermal conductivity. The polycrystalline material undergoes hydrolysis in aquatic and composting environments with minimal cytotoxicity ...

Facile and Rapid Fabrication of Thermoelectric Legs via Filtration of Doped Polymer Suspension
A vacuum‐filtration method using polymer‐dopant suspensions enables rapid fabrication of tens‐of‐micrometers‐thick, uniformly doped polymer films. Excess dopants and short‐conjugated polymer chains are effectively removed during filtration, reducing structural and energetic disorder.

Abnormal spin Seebeck effect near compensation temperature in Tb3Fe5O12 garnet films
We report the abnormal spin Seebeck effect (SSE) observed in Tb3Fe5O12(TbIG)/Pt heterostructures near the compensation temperature (T comp) of TbIG. As the temperature approaches T comp from room temperature, a rapid decline is shown in the spin Seebeck ...

Nanostructured titania:carbon black hybrid films, fabricated via water‐based slot‐die coating, show stable thermoelectric performance under light irradiation but degrade under high humidity. Operando grazing incidence small‐angle X‐ray scattering reveals humidity‐induced morphological changes correlating with reduced Seebeck coefficients.

Thickness dependence on dynamical spin injection driven by thermal effects in CoFeB/Pt bilayer
In ferromagnetic metal (FM)/non-magnetic metal (NM) bilayer structures, dynamical spin injection is primarily attributed to spin pumping at the interface.

Cadmium and Zinc‐Doped p‐type Sb2Se3 Single Crystals and Solar Cells
Cd and Zn were assessed as candidate p‐type dopants in Sb2Se3 single crystals in concentrations between 1016‐1020 cm−3. Both are effective in inducing p‐type conductivity, however Cd doped crystals exhibit lower resistivity across a wider range of dopant levels.
