Coulomb coupled quantum dot arrays with staircase ground state configurationhave been proposed in literature for enhancing heat-harvesting andrefrigeration performance. However, due to their mutual Coulomb interaction, aperformance analysis of such systems remains complicated and necessitatesconsideration of microscopic physics using density matrix formulation. Howeverthe path of device analysis starting from the system Hamiltonian to densitymatrix formulation is complicated and lacks the simplicity and intuitive aspectof sequential electron transport conveyed by the quantum master equation (QME)approach. In this paper, starting from the system Hamiltonian and employing thedensity matrix formulation, I derive the QME of a system of three quantum dots,two of which are electro-statically coupled. The framework formulated in thispaper can be further extended to derive QME of systems with higher number ofCoulomb coupled quantum dots.
