| Abstract Scope |
Conventional inorganic thermoelectric materials are generally rigid due to strong ionic or covalent bonding, restricting their application in flexible electronics. This work employed a simple cold-pressing technique to produce flexible thermoelectric foils from melt-cast chalcogenide ingots with the chemical composition of Ag2S0.6Te0.4. The n-type Ag2(S,Te) foils can be thinned to below 0.3 mm through multiple steps of pressing without cracking, resulting in a composite structure of crystalline domains within an amorphous matrix that promotes mechanical flexibility and suppresses lattice thermal conductivity. Additionally, substitution with copper induces a transition from intrinsically n-type with a carrier concentration of 9.706×1018 cm-3 to p-type transport property, fulfilling the fabrication of p-n thermoelectric modules with matched material characteristics for improved device integration. This study presents a practical and scalable approach for developing deformable inorganic thermoelectric materials suitable for wearable technologies. |
