The the ionic cores itself that is the silicon atoms as well as the boron atoms or the phosphorus atoms that are present, they are not moving at room temperature at room temperature that is not we dont have sufficient energy to break the bonds, these are all covalent bonds to break those bonds and to get those atoms to diffuse across, there will be some minuscule diffusion, but that is that will be completely negligible in this scale.
