The formation of cavities on the crystal surface was observed during the growth of zinc (and cadmium) single crystals from the vapour phase in the presence of hydrogen. This effect which is most pronounced on the {0001}‐face is a result of the diffusion of zinc vapour in hydrogen and is considered to be due, according to the kinematic theory of the growth forms of crystals, to the inhomogeneous supersaturation over the crystal surface. The experimental results are in accord with C HERNOV'S theoretical considerations concerning the critical size above which the formation of a cavity occurs.
