The features with size at least in one direction 1 .mu.m growth method was
developed by modifying liquid phase epitaxy. Number of processes was
developed where duration and amplitude of the cooling pulse at the
substrate interface were chosen in order to form low-dimensional features
before system return to the equilibrium condition. This method allows
obtaining low-dimensional features with observed quantum effect such as
quantum layers, dots and superlattices. The shape of the features
strongly depends on substrate orientation, stress and growth conditions.
