Density Functional Theory Investigation of Thermal
· This work presents the density functional theory based investigations of two-dimensional carbon pnictides α-CX (X = N and P). Despite being from the group of the pnictide family there are significant differences in the trends of the electronic and vibrational properties of both systems. The calculated electronic band gaps are 3.77 eV and 1.79 eV for α-CN and α-CP respectively. The direct
