Liquid phase epitaxy (LPE) is an important technique to grow GaSb-based materials of good crystal quality. Normally, one has to lower the growth temperature below the liquid-phase liquidus temperature to realize supercooling of the liquid phase. Here we bring forth a new type of LPE, pressure- variation LPE (PV-LPE), where a varying pressure is used to realize supercooling of the liquid phase even though the growth temperature is kept constant. Calculations show that there exists a simple relationship between the liquid content and pressure, which theoretically illustrates that crystal growth could be easily controlled by changing the pressure.
