Physical properties of predicted Ti2CdN versus existing Ti2CDC MAX phase: An ab initio study
Abstract
<b>Highlights</b>- Ti<sub>2</sub>CdN is a predicted phase of MAX nanolaminate.- Physical properties have been studied for the predicted Ti<sub>2</sub>CdN phase.- Physical properties of isostructural Ti<sub>2</sub>CdC have been compared with Ti<sub>2</sub>CdN.- Existing Ti<sub>2</sub>CdC and predicted Ti<sub>2</sub>CdN show important mechanical and optical properties.<b>Abstract</b><i>Ab intio</i> calculations were done to investigate the structural, elastic, electronic and optical properties of the Cd-containing theoretically predicted MAX phase, Ti<sub>2</sub>CdN, in comparison with the isostructural and already synthesized phase, Ti<sub>2</sub>CdC. These calculations reveal that the substitution of C by N affects the lattice parameter c, whereas the lattice parameter a, remains almost unchanged. All the elastic constants and moduli increase when carbon is replaced by nitrogen. The elastic anisotropy in Ti<sub>2</sub>CdC is higher in comparison with that of Ti<sub>2</sub>CdN. Both these nanolaminates are brittle in nature. The calculated electronic band structures and density of states suggest that the chemical bonding in these two ternary compounds is a combination of covalent, ionic and metallic in nature. Electrical conductivity of Ti<sub>2</sub>CdC is found to be higher than that of Ti<sub>2</sub>CdN. The calculated reflectivity spectra show that both the MAX phases Ti<sub>2</sub>CdC and Ti<sub>2</sub>CdN have the potential to be used as coating materials to minimize solar heating.
