Query: High thermoelectric performance originating from the grooved bands in
  the ZrSe3 monolayer   Low-dimensional layered materials have attracted tremendous attentions due to
their wide range of physical and chemical properties and potential applications
in electronic devices. Using first-principles method taking into account the
quasiparticle self-energy correction and Boltzmann transport theory, the
electronic transport properties of ZrSe3 monolayer are investigated, where the
carrier relaxation time is accurately calculated within the framework of
electron-phonon coupling. It is demonstrated that the high power factor of the
monolayer can be attributed to the grooved bands near the conduction band
minimum. Combined with the low lattice thermal conductivity obtained by solving
the phonon Boltzmann transport equation, a considerable n-type ZT value of ~2.4
can be achieved at 800 K in the ZrSe3 monolayer.
