我们展示了一个热电纳米发电机（NG）由一个单一的Sb掺杂的ZnO微/纳米带，产生约1.94 nW的输出功率下的两个电极之间的温度差为30 K。将Sb掺杂ZnO微带作为NG键合在玻璃衬底上，得到了10 mV的输出电压和194 nA的输出电流。单个Sb掺杂ZnO微带显示出约-350 μ V/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展示了其作为自供电温度传感器工作的潜力，复位时间约为9 s，
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 30K 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 mu V/K and a high power factor of about 3.2 x 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,
