Abstract
Aiming at selective regrowth, the effect of Tertiarybutylchloride (TBC1) on the electrical properties of LP-MOVPE grown Fe-doped InP layers was investigated in dependence of growth temperature and pressure, which varied from 635°C to 700°C and 20 mbar to 100 mbar, respectively. Fe-doping variation from 2·1016 cm-3 to 1·1017 cm-3 resulted in resistivity values in the 108 ?·cm range. In the case of TBC1 addition, enhanced Fe-incorporation was observed, however, resistivity remained in the same range. Thus, TBC1 may be applied for morphology improvement without compromising the semi-insulating behaviour of the InP:Fe material.
