Fig. 4

a The most stable arrangement of the terminated Ti2NTx layers by oxygen atoms for two adjacent Ti2N layers. The solid line denotes the lateral size of the supercell (top view). b Interlayer binding energy curve of Ti2NO2 layers. The interlayer binding energy decreases as the number of layers increases, reaching a value of − 16.6 meV/atom for an infinite number of layers. The black line fitted to the data is presented, and the extrapolated value for an infinite number of layers is indicated
