Overview

This investigation reports the optoelectronic and thermoelectric properties of Cu2MSnX4 compounds, suggesting their potential applications in energy conversion devices.

Key Points

  • The study aims to explore the structural and functional properties of Cu2MSnX4 compounds to assess their suitability for optoelectronic and thermoelectric applications.
  • First-principles calculations using the FP-LAPW framework of density functional theory (DFT)
  • Structural optimization to analyze energetically favorable configurations
  • Thermoelectric analysis calculating Seebeck coefficients and thermal conductivities
  • Direct band gaps ranging from 0.553 to 1.477 eV indicating suitability for visible-light absorption
  • Strong dielectric polarisation and absorption coefficients exceeding 10⁴ cm−¹ in the visible region
  • Sulfide analogues exhibit higher Seebeck values and lower thermal conductivities compared to selenides
