We have investigated the behavior of dynamical thermal conductivity of doped biased bilayer graphene for AA-stacking as a function of frequency in the context of tight-binding model Hamiltonian. In this work, it has considered frequency dependence of temperature gradient. Green’s function approach has been implemented to find the behavior of thermal conductivity of bilayer graphene within Kubo linear response theory. Different behaviors have been seen for thermal conductivity due to different frequency. Also thermal conductivity versus bias and temperature has investigated. Dynamical thermal conductivity decreases with chemical potential, bias voltage and temperature, while it has a relative fluctuation with frequency at high bias voltage and high temperature.
