Transverse thermoelectric performance of the artificially tilted multilayer thermoelectric device (ATMTD) is very difficult to be optimized, due to the large degree freedom in device design. Herein, an ATMTD with Fe and Bi2Te2.7Se0.3 (BTS) materials was proposed and fabricated. Through high-throughput calculation of Fe/BTS ATMTD, a maximum of calculated transverse thermoelectric figure of merit of 0.15 was obtained at a thickness ratio of 0.49 and a tilted angle of 14°. For fabricated ATMTD, the whole Fe/BTS interface is closely connected with a slight interfacial reaction. The optimizing Fe/BTS ATMTD with 12 mm in length, 6 mm in width and 4 mm in height has a maximum output power of 3.87 mW under a temperature difference of 39.6 K. Moreover the related power density per heat-transfer area reaches 53.75 W·m−2. This work demonstrates the performance of Fe/BTS ATMTD, allowing a better understanding of the potential in micro-scaled devices.

“…Наибольшее распространение получили датчики, основанные на температурной зависимости электрического сопротивления чувствительного элемента и термоэлектрические датчики на основе эффекта Зеебека. К первому типу относятся тонкопленочные датчики сопротивления [7], а ко второму коаксиальные термопары [8], датчики на основе тонкой анизотропной пленки из высокотемпературных сверхпроводников [9,10] и хрома [11], а также датчики на основе анизотропных термоэлементов из висмута и слоистых металлических структур [12,13]. До недавнего времени основным средством измерения являлись тонкопленочные датчики сопротив-ления.…”

“…Отличительной особенностью термоэлектрических датчиков на основе анизотропных пленок толщиной ∼ 1 µm является быстрое (∼ 0.1−1 µs) установление стационарного распределения температуры в чувствительном элементе. По этой причине электрический сигнал датчика пропорционален проходящему через него тепловому потоку и обработка результатов измерений сводится к умножению зарегистрированного в эксперименте сигнала на известный калибровочный коэффициент [10,11].…”

An analysis of main features of unsteady heat flux measuring in shock tubes experiments with a characteristic process time of ~1 μs - 1 ms using sensors based on anisotropic bismuth thermoelements is made. The heat flux behind the reflected shock wave and at the blunt body stagnation point has been measured. Testing of the heat flux calculation method was carried out. The difference between the experimental data and the theoretical value of the heat flux does not exceed 50%. The possible reasons influencing the magnitude of measurement uncertainty are analyzed. The experiments performed have shown the applicability of a sensor based on anisotropic thermoelements and the method for calculating the heat flux from its electrical signal for typical conditions of experiments on shock tubes.

“…The most widespread are sensors based on the temperature dependence of the electrical resistance of the sensitive element and thermoelectric sensors based on the Seebeck effect. The first type includes thin-film resistance sensors [7], and the second type includes coaxial thermocouples [8], sensors based on a thin anisotropic film of high-temperature superconductors [9,10] and chromium [11], as well as sensors based on anisotropic bismuth thermoelements and layered metal structures [12,13]. Until recently, thin-film resistance sensors were the main means of measurement.…”

“…A distinctive feature of thermoelectric sensors based on anisotropic films ∼ 1 µm thick is the rapid (∼ 0.1−1 µs) establishment of a stationary temperature distribution in the sensitive element. For this reason, the electrical signal of the sensor is proportional to the heat flux passing through it, and the processing of the measurement results is come down to multiplying the signal recorded in the experiment by the known calibration coefficient [10,11].…”
