Contribution

It introduces a simple solvo-thermal synthesis method for n-type SnSe$_{1-x}$ and explores its thermoelectric properties, suggesting the feasibility of an all SnSe thermoelectric module.

Findings

Low thermal conductivity observed in synthesized material.

Significant thermopower measured between 100-400 K.

Potential for developing all SnSe thermoelectric devices.

Abstract

We report the synthesis of n-type SnSe$_{1-x}$ using a self-sacrificial, facile, solvo-thermal synthesis route. Electrical and thermal transport measurements suggest a low thermal conductivity and a significant thermopower in the temperature range 100 - 400\,K. We also propose the possibility of developing an all SnSe thermoelectric module.
