| Abstract Scope |
This study focuses on the mechanical properties of cold-pressed Ag2S1-xTex-based thermoelectric foils, which exhibit outstanding flexibility compared to conventional inorganic thermoelectric materials. While most traditional compounds fracture at strains exceeding 3% due to their rigid crystal structures, the foils developed here can endure tensile strains over 15% without cracking. This research further explores how cold pressing influences thermoelectric properties by altering the microstructure, leading to a hybrid configuration of dispersed crystalline domains within an amorphous matrix. This configuration not only improves flexibility but also enhances phonon scattering, contributing to reduced lattice thermal conductivity. The study further correlates the strain tolerance with grain boundary behavior, crystallinity, and defect distribution, revealing that structural disorder plays a key role in enabling both mechanical resilience and stable thermoelectric performance under deformation. These findings provide a viable route toward designing flexible thermoelectric materials for future wearable applications. |
