In this work, we study topological properties of a gated d-wave (MTI/SC) heterostructure. The phase diagram of the system is obtained by employing the Kubo formula. The existence of Majorana edge modes in the presence of electrical gating has been shown in d-wave topological superconductors. A Green's function formalism has been employed for the detection of Majorana edge modes and their localization properties have been investigated.
