| Abstract |
A micro thermoelectric device was processed by electroplating the n-type Bi-Te nanowires and p-type Sb-Te nanowires into an alumina template with 200 nm pores. Power generation characteristics of the micro devices composed of the Bi-Te nanowires, the Sb-Te nanowires, and both the Bi-Te and the Sb-Te nanowires were analyzed with applying a temperature difference of 40℃ across the devices along the thickness direction. The n-type Bi-Te and the p-type Sb-Te nanowire devices exhibited thermoelectric power outputs of 3.8×10(-10) W and 4.8×10(-10) W, respectively. The output power of the device composed of both the Bi-Te and the Sb-Te nanowires decreased to 1.4×10(-10) W due to a large electrical resistance of the Cu electrode connecting the Bi-Te nanowire array with the Sb-Te nanowire array. |
