N-type Bi2Te3 and p-type Sb2Te3 thermoelectric thin films have been prepared by RF and DC co-sputtering. The Seebeck coefficient of n-type Bi2Te3 and p-type Sb2Te3 thin films is about -122 μVK-1 and 108 μVK-1, the power factor is about 0.82×10-3 Wm-1K-2 and 1.60×10-3 Wm-1K-2. Then, the films have been selected to fabricate the thin film thermoelectric generator. The results show that the open-circuit voltage of 12.2 mV and the output power of 3.32 μW are obtained for a thin film generator with the temperature difference at 60 K.

The performance of thermoelectric (TE) thin films strongly depends on the substrates. In our previous study, we investigated the power factor (PF) 1.78 mW/[Formula: see text] at 700 K in [Formula: see text] thin film grown on single crystalline Si, comparable to the state of art in other TE thin films. Such boosted PF originates mainly from the significantly enhanced Seebeck coefficient, correlated with the contribution of the Si substrate. In this paper, the PF has been prominently optimized up to 12.5 mW/[Formula: see text] at 668 K by adjusting the thickness of [Formula: see text] film in the [Formula: see text]/Si system, which could be understood in the frame work of parallel slab model. Experimentally, the effective TE properties were susceptible to the substrate–film interface. The existence of Mo in [Formula: see text] film might limit the formation of [Formula: see text] interfacial layer. These results suggest a simple, low-cost, scalable technique route to explore highly effective TE devices.

AbstractLow-dimensional materials have recently attracted much interest as thermoelectric materials because of their charge carrier confinement leading to thermoelectric performance enhancement. Carbon nanotubes are promising candidates because of their one-dimensionality in addition to their unique advantages such as flexibility and light weight. However, preserving the large power factor of individual carbon nanotubes in macroscopic assemblies has been challenging, primarily due to poor sample morphology and a lack of proper Fermi energy tuning. Here, we report an ultrahigh value of power factor (14 ± 5 mW m−1 K−2) for macroscopic weavable fibers of aligned carbon nanotubes with ultrahigh electrical and thermal conductivity. The observed giant power factor originates from the ultrahigh electrical conductivity achieved through excellent sample morphology, combined with an enhanced Seebeck coefficient through Fermi energy tuning. We fabricate a textile thermoelectric generator based on these carbon nanotube fibers, which demonstrates high thermoelectric performance, weavability, and scalability. The giant power factor we observe make these fibers strong candidates for the emerging field of thermoelectric active cooling, which requires a large thermoelectric power factor and a large thermal conductivity at the same time.
