The growth conditions have been studied for InGaAsP LPE layers grown on (100) InP substrates using the two-phase melt technique. It has been found that the melt-compositions to obtain the 1.1 ㎛ InGaAsP lattice-matched to InP are X_Ga = 0.00417 and X_As = 0.032 when the growth temperature is 630℃ and the cooling rate 0.5℃/min. In this case, the solid-compositions x and y are 0.9 and 0.23, respectively. Also the influences of variations of the Ga and As atomic fraction in the liquid, X_Ga^L and X_As^L on the bandgap energies and the lattice constants have been investigated. The surface morphology and the growth thickness of InGaAsP LPE layers have also been studied.
