18. We have assumed above that the distortion of the unit cell takes place along the same axis all through the sample, i.e., all the unit cells have their c axis along, say, the z direction. This is reasonable, since there would be enormous elastic costs involved in having adjacent unit cells distended along different directions. Accordingly, the displacement can only be along the z axis, but it can be either up or down.
