Fe-doped semi-insulating In1−x Gax Asy P1−y (0≤y≤1, y=2.2x) epitaxial layers lattice matched to InP with nearly intrinsic carrier concentrations have been successfully grown over the entire composition range by liquid phase epitaxy. Maximum resistivities as high as 8×107 Ω cm for InP, 2×105 Ω cm for InGaAsP (y=0.57), and 2×103 Ω cm for InGaAs (y=1) have been achieved. The critical growth temperature necessary to obtain semi-insulating layers significantly decreased as the composition was varied from y=0 to y=1. The Fe doping characteristics are well defined by the composition dependence of the Fe distribution coefficient.
