Abstract

The thermal transport properties of black and blue phosphorene nanoribbons and in-plane heterostructures are systematically investigated by non-equilibrium Green's-function method. Both edge shape and width have a sensitive influence on the thermal conductance of pristine black and blue phosphorene nanoribbons and they all exhibit a clear anisotropic thermal performance. Interestingly, the in-plane heterostructures possess a tunable thermal conductance which depends on the percentage of black phosphorene nanoribbons and the way how they are linked. These findings will provide new applications in nanoelectronic and thermoelectric devices based on phosphorene.
