Abstract
Based on the full electron–phonon couplings analysis and the solution to the Boltzmann transport equation, Sb<sub>2</sub>Te<sub>2</sub>Se monolayer is expected to be a high-performance thermoelectric material with high <italic>zT</italic> values of 1.28/1.86 for p/n doping at 300 K, respectively.
