Abstract: The corrosiveness of bismuth telluride-based thermoelectric materials (n-type single-phase alloy and a nanocomposite with MoS2 nanoinclusions), in 0.1 molar solution of sodium chloride (NaCl), was investigated. The electrochemical impedance spectroscopy curves obtained after 1, 24,… read more here.

Abstract: In polycrystalline bismuth-telluride-based thermoelectric materials, mechanical deformation induced donor-like effect can introduce a high concentration of electrons to change thermoelectric properties through the evolution of intrinsic point defects. However, the evolution law of these point… read more here.

DOI: 10.1093/nsr/nwae329

Abstract: ABSTRACT Thermoelectric Peltier coolers (PCs) are being increasingly used as temperature stabilizers for optoelectronic devices. Increasing integration drives PC miniaturization, requiring thermoelectric materials with good strength. We demonstrate a simultaneous gain of thermoelectric and mechanical… read more here.
