A novel method for synthesizing device-quality alloys and ordered phases in a Si\u2014Ge\u2014Sn system uses a UHV-CVD process and reactions of SnD4 with SiH3GeH3. In the process, a biomass contained within a fermentation medium is fermented with an inoculum comprising a mixed culture of microorganisms derived the rumen contents of a rumen-containing animal. When executed by the host processor, the BIOS extension code copies the server program embedded within it to a new location in host memory, and then hooks the new location of the server program to a pre-selected interrupt of the host computer system to cause the host processor to initiate execution of the server program on the host computer system upon a subsequent occurrence of that interrupt. At least generally equal ion distribution across the target regions is achieved by differing the ion flow rates of the neutralization streams.
