Non-Linear Theory of Alloy Phase Separation in Open Systems: Kinetic Phase Transitions Between 1D and 2D Structures

Abstract

The steady state phase diagram applies to any alloy. We explain a large variety of structures. e.g.. the ID structure in InAlAs modulated along 110 the 2D structure in lnGaAsP modulated in 100 and 010 directions. and a kinetic phase transition in InAlAs between the growth of a 2D structure modulated along 100 and010 and the growth of a 1D structure modulated along 110. Our results demonstrate a possibility to tune the structure between 1D and 2D ones by varying growth velocity and temperature.
