New model of LPE growth: Growth rate calculation
Expressions for the LPE growth rate are developed on the basis of the new steady-state growth model assuming nucleation in the solution. The solution thickness can be calculated at which the LPE growth rate reaches a maximum for any solution cooling rate. The initial and the volume nucleation parameters, formation times, critical supersaturations and supercoolings of the solution have been determined from experimental GaP and GaAs LPE data. Calculated growth rates fit very closely with experimental rates of GaP and GaAs LPE growth.
