The properties of impurity bound magneto-acoustic strong-coupling polarons in monolayer graphene are examined. The energies of the ground state of the impurity bound magneto-acoustic polaron were obtained by using the linear combination operator and the well-known Lee-Low-Pines transformation methods. By employing the quantum statistics theory, the temperature effects on the ground state energy of magneto-acoustic polarons in monolayer graphene were calculated. The results of the numerical model with regards to the temperature, Coulombic impurity potential, Debye cut-off wavenumber and magnetic field strength are discussed, and it was revealed that the tuning of these factors can offer a way of adjusting the ground state energy of the magneto-acoustic polaron.
