Chalcogenide semiconductors and semimetals continue to be of prime interest for thermoelectric applications in power generation. As another representative of this broad class of materials, tetragonal InTe has recently emerged as a promising candidate due to its very limited ability to transport heat leading to high thermoelectric performance near 800 K in polycrystalline samples. However, little is known on the basic physical mechanisms governing its electronic and thermal properties, an in-depth study of which requires the growth of single crystals. Here, we report a detailed investigation of the transport properties of InTe single crystals grown by the Bridgman–Stockbarger technique over a wide range of temperatures (5–800 K).
