The DFT calculations result for a possible stacking configuration of the 5CB on the BP and the P4O2. (a,b) The top view of the BP crystal lattice and the P4O2. (c,d) The 5CB molecule aligned parallel to the zigzag and the armchair orientation on the BP, respectively, with adsorption energy and the distance between the centre of the LC and the BP lattice. (e,f) The 5CB align along the zigzag and the armchair orientation on the P4O2, respectively, with adsorption energy and the distance between the centre of the LC and the BP lattice.
