(a) The frequency dependent lattice thermal conductivity of borophene at five typical temperature. (Inset) The contribution of phonon modes with different frequencies to the total lattice thermal conductivity of borophene as a function of temperature. (be) Some typical phonon modes of borophene together with their frequencies at the Γ point. The arrows denote the atomic displacement directions.
