“…Thermal cycling tests were performed to assess the operational reliability of the assembled TEMs, considering the presence of a power on/off switch, which creates the conditions closer to thermal cycling in actual operation. 36 For the case of the module assembled at 50 N pressure, the resistance initially remains constant and then starts to increase at a fixed slope after 350 cycles. This behavior was explained in our previous work, attributing the resistance growth to the generation and expansion of interfacial cracks.…”

“…In the real service environment, the degradations due to the thermal cycles, [66] oxidation, [67] humidity, salt mist, and many others need to be considered. Most TE materials are metal-based semiconductors (except oxide compounds) and sensitive to oxygen, especially at high service temperatures.…”

“…Chalcogenides are being actively studied as modules for various devices such as wearable devices and generators for vehicles [9,10]. Defect engineering, such as doping and nanostructuring, is an effective approach for reducing κ latt by † increasing point-defect phonon scattering [11][12][13].…”
