The diffusion process of H atom follows a similar shear-assisted process, with the difference that the binding sites are now the B atoms, see It is important to note that proton carries its charge during the hopping process: even though the proton is nearly neutralized while being bound to N atom, when dislocating to the next N adsorption site, it leaves the electron behind. The atomic charge analysis shows that the electronic configuration of the layer recovers to the pristine state after the proton has left.
