Key Points

This research aims to enhance the thermoelectric performance of InSe-based materials by manipulating chalcogen substitution and breaking local inversion symmetry.
Investigated structural, mechanical, electronic, and thermoelectric properties of InSe-based layered materials.
Explored chalcogen substitution (X,Y=S,Se,Te) in hexagonal phase materials.
Analyzed local inversion symmetry effects on properties.
Chalcogen substitution significantly improved thermoelectric performance, enhancing figure of merit (ZT).
Broken local inversion symmetry led to notable electronic property changes, increasing conductivity.
Demonstrated that structural modification optimizes thermoelectric efficiency dramatically.
