n-Type Mg3Sb2-xBix alloys have been regarded as promising thermoelectric materials due to their excellent performance and low cost. For practical applications, the is not only factor that should be taken into consideration. In addition, chemical thermal stabilities of material are equal importance for module design. Previous studies reported were unstable in an ambient environment. this work, we found reacted with H2O O2 at room temperature formed amorphous Mg(OH)2/MgO crystalline Bi/Sb. The...
<p>Thermoelectric coolers (TEC) play a critical role in establishing substantial temperature differences required for cooling photoelectric detectors. While single-stage devices suffice moderate cooling, multi-stage TECs are indispensable when pursuing cryogenic below 200 K. The existing TECs, however, remain constrained by their exclusive dependence on Bi<sub>2</sub>Te<sub>3</sub>-based alloys. Recently, the n-type...
Thermoelectric cooling plays an essential role in precisely controlling the temperature of electronics. Characterizing performance thermoelectric coolers (TECs) is great significance for development advanced solid-state devices. However, existing setup characterizing TECs has mainly been limited to near room range. Herein, we report a new that capable across broad range (80-350 K). With precise and steady control hot-side temperature, measurements coefficient maximum difference at have...
