As layers were grown on semi-insulating Fe-doped InP (100) substrates by low pressure metalorganic chemical vapor deposition (LP-MOCVD). The growth was performed using TMIn

TMGa

and AsH

as growth precursors of In

and As

respectively

in a horizontal reactor. The substrate on a graphite susceptor was heated by inductively coupling radio frequency power

the growth temperature was detected by a thermocouple

and the reactor pressure was kept at 110

Pa. Thickness of In

As layer for all samples was kept to be 300 nm. In our experiments

the growth temperature of In

As layer and InP substrate was varied from the growth temperature

As layer was different. It was analyzed that the growth temperature of In
