Abstract
A piston-type device for liquid-phase epitaxy of AIIIBV semiconductor compounds has been modified. The possibility of controlling the impurity concentration gradient, which creates internal electric fields in the photodetecting and active regions of semiconductor structures, is demonstrated. This control is achieved by selecting the appropriate extrusion pattern of the solution–melt.
