Abstract
The authors investigate the phonon-limited electronic transport using the first-principles method with Boltzmann transport theory. The light effective mass and weak electron-phonon coupling result in the high hole carrier mobility in 1T'' MoSe2. It combines with the large Seebeck coefficient to illustrate the thermoelectric application potential.
