Abstract: Abstract GeTe-based alloys have been considered promising p-type thermoelectric materials at medium temperatures (300−800 K). Indium (In), an effective dopant that introduces resonant states, and selenium (Se), which reduces lattice thermal conductivity, were combined. The process… read more here.
