A device for forming a Group III-V semiconductor on a substrate. The device has a primary chamber comprising a substrate and a heat source for heating the substrate to a first temperature. A secondary chamber comprises a metal source and a second heat source for heating the secondary chamber to a second temperature. A first source is provided which is capable of providing HCl to the secondary chamber wherein the HCl and the metal form metal chloride. A metal-organic source is provided. A metal chloride source is provided which comprises a metal chloride. At least one of the metal chloride, the metal-organic and the second metal chloride react with the nitrogen containing compound to form a Group III-V semiconductor on the substrate.
