Earth Abundant, Non-Toxic, 3D Printed Cu2-xS with High Thermoelectric Figure of Merit
收藏资源简介：
Dataset for: Earth Abundant, Non-Toxic, 3D Printed Cu<sub>2-x</sub>S with High Thermoelectric Figure of Merit The toxicity, earth abundance and manufacturing costs of thermoelectric materials are three leading reasons why thermoelectric generators are not used in wide scale applications. This is the first ever paper to tackle all three of these problems at once. A pseudo-3D printing technique is combined with Cu<sub>2-x</sub>S based inks to yield bulk samples capable of being using in traditional architecture thermoelectric generators. These bulk samples are characterized over a wide temperature range in XPS, which reveals a curing temperature of 550 K yields pure Cu<sub>2-x</sub>S samples. The thermoelectric properties of these samples are tested over a wide temperature range, with a peak ZT of 0.63 ± 0.09 being recorded at 966 K.
