Modulating Solid‐Solution Solubility to Enhance Thermoelectric Performance and Maintain Structural Stability in Phase‐Transition Silver Chalcogenides (Small 24/2025)
Source abstract
Abstract
Silver Chalcogenides In article number 2410583, Hsin-Jay Wu and co-workers uncover the mechanism of silver whisker growth and propose a method to inhibit it. By modulating the solubility of the silver solid solution through dilute Ga doping, the Ga-Ag2+xTe achieves improved thermoelectric performance, reaching a conversion efficiency of 2.3% with a ΔT of 300 K, and remains free of whiskers after high-temperature testing, resulting in a thermally stable, high-performance thermoelectric device.
