We demonstrate a thermoelectric nanogenerator (NG) made from a single Sb-doped ZnO micro/nanobelt that generates an output power of about 1.94 nW under a temperature difference of 30 K between the two electrodes. A single Sb-doped ZnO microbelt was bonded at its ends on a glass substrate as a NG, which can give an output voltage of 10 mV and an output current of 194 nA. The single Sb-doped ZnO microbelt shows a Seebeck coefficient of about -350 μV/K and a high power factor of about 3.2 × 10(-4) W/mK(2). The fabricated NG demonstrated its potential to work as a self-powered temperature sensor with a reset time of about 9 s.
我们展示了一种由单个掺 Sb 的 ZnO 微/纳米带制成的热电器件 (NG),在两个电极之间的温差为 30 K 的情况下,产生约 1.94 nW 的输出功率。单个掺 Sb 的 ZnO 微带的两端被键合在玻璃基底上作为 NG,可以给出 10 mV 的输出电压和 194 nA 的输出电流。单个掺 Sb 的 ZnO 微带表现出约 -350 μV/K 的塞贝克系数和约 3.2×10(-4) W/mK(2) 的高功率因数。所制造的 NG 表现出作为自供电温度传感器的潜力,其复位时间约为 9 s。
