Abstract: | Problems concerned with the formation of multilayer strained-layer heterostructures by “capillary” liquid-phase epitaxy with
forced hydraulic replacement of the solutions in the growth channel are analyzed. It is shown for short contact times between
the solutions and the crystallization surface that the character of their flow in the channel plays an important role in the
achievement of uniformity in the physical characteristics of the layers grown. Theoretical estimates of the hydrodynamic stability
of solutions moving in narrow channels are performed for several III-V systems. A mathematical model, which permits simulation
of the conditions under which strained-layer heterostructures are fabricated, is developed. It takes into account diffusive
and convective mass transport in the liquid for various flow regimes in the capillary and the displacement of the heterogeneous
equilibria in the system under the influence of elastic stresses.
