2007年12月1日 · The thermogravimetric analysis (TGA) (Perkin-Elmer, Pyris-1) and differential thermal analysis (DTA) (Perkin-Elmer, Pyris-7) of SnSe samples were carried out in an inert nitrogen atmosphere in the temperature range of 300–1273 K.

2021年8月2日 · Single-crystal tin selenide (SnSe) was discovered to exhibit a high ZT of roughly 2.2–2.6 at 913 K, but more practical and deployable polycrystal...

2020年6月1日 · High-quality (400)-textured SnSe polycrystalline thin films are one-step synthesized by chemical vapor deposition. In-situ in-plane TE measurement shows that the obtained SnSe films possess a dimensionless ZT of 0.15 and a power factor of 0.322 mW m −1 K −2 at 550 K, showing SC level TE performance at low temperatures.

2018年6月21日 · In this paper, we investigate the use of thermal evaporation to manufacture thin films of SnSe. Thermal evaporation is a relatively cheap and facile fabrication technique for thin film devices, in contrast to most SnSe fabrication techniques for thermoelectric applications already presented in the literature.

At higher annealing temperatures (800 K & 1000 K), the SnSe thin films exhibit higher electrical resistivity, comparable Seebeck coefficient, and thus lower power factor. In situ X-ray diffraction reveals that annealing at temperatures above 850 K leads to a reversible phase transition from the Pnma structure to the Cmcm structure. Cited by

2019年2月20日 · We show that the strong textures of the thin films in the b–c plane originate from the transition of two dimensional SnSe 2 to SnSe. This composition change-driven transition offers wide...

2018年8月1日 · The TGA and DTA of SnSe are important indicatives for the potential use of SnSe as a thermoelectric material in the device for the real application. Considering the instability of SnSe at high temperature, SnSe-based thermoelectric materials …

2024年4月25日 · The differential scanning calorimeter (DSC) and thermo-gravimetric analysis (TGA) analysis provide insights into the thermal behavior and decomposition processes of PVA and SnSe in the specific temperature range.

2021年1月15日 · Here, we report that the physical properties of SnSe crystals with nano to submicron scale are drastically modified by atmospheric annealing.

Solid solution SnSe0.75S0.25 has potential to improve thermoelectric performance via ultra-low thermal conductivity as compared to the pristine SnSe which originates from phonon scattering due to...
