The applications of Heusler compounds in thermoelectric made them valuable for the theoreticians and experimentalists. In this paper thermoelectric properties of Co2MnAl, Co2MnSi and Co2MnGe full-Heusler compounds have been reviewed. The calculations were done by using BoltzTrap code which depends upon the Boltzmann semi-classical transport equation. Seebeck coefficient, electrical conductivity, and thermal conductivity for Co2MnSi and Co2MnAl were calculated by considering both magnetic phases. Co2MnSi was found to be half-metallic in ferromagneic phase and had the highest value for the power factor (2.9×10-3Wm-1k-2). Co2MnGe was found to be half-metallic and had the smallest value for figure of merit at room temperature. The calculated values for Seebeck coefficient for Co2MnSi and Co2MnGe were 40×10-6 VK-1 and 16.7×10-6 VK-1 respectively.
