Here, E[Ti 2 CST] is the total energy of Ti 2 CST monolayer, E[Ti 2 C] is the total energy of Ti 2 C MXene, E[S] represents the total energy of S atom in its bulk material and E[T] is the total energy of Se (O) atom in their bulk (gas) compounds. As shown in Table , E form values are negative for both materials indicating synthesizing these materials are highly possible. We also carried out spin polarized DFT calculations to investigate the magnetic nature of the structures. DFT provides zero magnetic moment for each atom of the unit cells implying that the nonmagnetic ground states are very stable.
