The study resolves the energy band makeup and step stability of the delafossite compounds AgMO2 (place M = Al, Ga, In) using the TB-LMTO form and local density estimate. The predictions consider the demeanor states of the atoms and the optimized c/a percentage of the compounds. The total energy was deliberate as a function of discounted volume and equipped with the Birch Murnaghan equating of state. The results show that the 3R polytypes are more resistant than the 2H polytypes at ambient environments. The electronic band constructions of the compounds have an indirect band break and the densities of states are governed by the Ag 4d states and O 2p states. The band breach values for the AgMO2 compounds decrease in the order of AgAlO2, AgGaO2, and AgInO2 for two together the 2H and 3R polytypes. The optical characteristics of the AgMO2 compounds were more studied utilizing the full potential design. The study specifies new insights into the photoelectric and optical features of TCOs with potential uses in optoelectronics.
