ABSTRACT:
A method and system for growing a layer of semiconductor material is disclosed. The method can be used to grow a layer of a semiconducting material comprising at least one Group III element, nitrogen and at least one other Group V element as constituent elements thereof, the method comprising providing a reactor and supplying precursors to the reactor. The precursors include a precursor for each of the at least one Group III element, a precursor for the nitrogen, a precursor for each of the at least one Group V element other than nitrogen, and a precursor for an element having a stronger bond strength with nitrogen than each of the at least one Group III element has with nitrogen. The method can be implemented in, for example, a metal organic chemical vapor deposition (MOCVD) reactor.
