Defect Driven Electronic Structure Reconfiguration and Hierarchical Phonon Suppression in Ag2Se Thermoelectrics

Advanced Science, EarlyView.
Indium substitution in Ag2Se nanocrystals simultaneously tailors electronic structure and lattice dynamics. Fermi‐level upshift and band‐gap narrowing enhance electrical transport, while defect‐induced lattice softening intensifies phonon scattering and suppresses lattice thermal conductivity.

Bulk Superconductivity in Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ Induced by Annealing in Se and S Vapor

, 2013
We reported that bulk superconductivity in Fe$_{1+y}$Te$_{1-x}$Se$_{x}$ can be induced by annealing in Se and S vapor. The well-annealed samples show a large critical current density, emph{J}$_c$ $\sim$ 2 - 4 $\times$ 10$^5$ A/cm$^2$.
