Chalcogenide semiconductors continue to be of prime interest for designing novel efficient materials for energy-conversion applications. Among them, the narrow-band-gap p-type semiconductor InTe exhibits high thermoelectric performance that mostly stems from its poor ability to transport heat. Here, we show that its thermoelectric figure of merit can be further enhanced by finely tuning the hole concentration through Pb doping. X-ray diffraction and scanning electron microscopy performed on the polycrystalline series In1-xPbxTe confirm that Pb substitutes for In with an estimated solubility limit below 1%.
