generalized semiclassical boltzmann formalism for an anisotropic system, borophene

In a systematic framework, we have calculated the electrical conductivity and thermoelectriccoefficients of borophene in the presence of the short-range, long-range charged impurity and theshort-range electro-magnetic (srem) scatterers, by using the exact solution of the boltzmann transportequation within the linear-response theory. contrary to the large electron-hole asymmetry inborophene, its electron-hole conductivity is nearly symmetric. interestingly, in the case of shortrangescattering, just like graphene, the conductivities of borophene were found to have constantvalues, independent of the chemical potential, while the conductivities of the srem scatterers arelinearly dependent on the chemical potential. regardless of the impurity type, the electrical conductivityof borophene is highly anisotropic, while the seebeck coefficient and figure of merit (zt) areisotropic. this high anisotropy ratio together with the large figure of merit, suggest that boropheneis promising for the thermoelectric applications and transport switching in the dirac transportchannels.
