摘要

Abstract

SnI

perovskites

which can be created using printing technology

are environmentally friendly thermoelectric materials

but their applications are limited by unsatisfactory thermoelectric efficiency and structural stability. In this work

SnI

perovskites are processed by applying high pressure with shear strain for the first time

resulting in better structural stability

enhanced electrical conductivity and the Seebeck coefficient with CH

SnI

tube structures after processing. First-principles calculations verified the reasonable changes in lattice constants

electronic band structures

electrical conductivity and the Seebeck coefficient. The present study demonstrates a potential strategy to improve the structural and thermoelectric properties of CH

SnI

and uncovers the possible mechanism.
