DIAMOND FORCED DIFFUSION PLANT
THE OPPORTUNITY
Diamond film development is in the initial stages that silicon was in during the 1960's. Considerable
experimental work continues in producing film of consistance and purity. However, certain amounts are
being sold yearly, mostly for hardening surfaces and for cutting tools.
The most exciting prospects for diamond film in the future will be diamond film doped with certain
elements such as boron, phosphorous, and lithium. The boron doped diamond will give the diamond film
a positive charge. The phosphorous doped film a negative charge. Doping of diamond whether positive
or negative lends the diamond film unusual qualities.
Rhombic Corporation of the United States has the advantage of working directly with Boris Spitsyn,
known as the founding father of diamond research. In 1991, a Rhombic principal was the first western
scientist to visit the former Soviet Union's top secret weapon's laboratories at Arzamas 16 and Helyabinsk
70. He and other company scientists and engineers have used Dr. Spitsyn's diamond film to craft an
electrical cell similar to solar cells that directly converts nuclear energy to electricity and allows for the
development of portable nuclear power sources. The cell is the key to process known as "the nuclear
lightbulb" which would produce electricity at least twice the efficiency as the current process.
The opportunity is now in the possession of Rhombic. Rhombic Corp. has on staff several of the world's
top scientists in a diamond film development. The company has completed a significant patent
application evolving forced diffusion of impurities into diamond. The Company, in regard to the various
applications of doped diamond film, is initiating other patent applications. Among these uses for
consideration is a new generation of integrated circuits, high power diamond switches and diodes,
transistors, diamond TV screens and computer monitors, and the interesting possibility of coloring
ordinary diamonds blue, green, yellow, and even red.
After developing methods of diffusing impurities into the diamond crystal lattice using the forced
diffusion technique, considerable work has continued in the laboratory on the fusion of boron, nitrogen,
and lithium into the diamond crystal. The results were so compelling that the company began a
systematic study of diffusing into diamond other impurities such as oxygen, chlorine, nitrogen, and
fluorine. Besides the success of introducing different elements into diamond, it was proved that forced
diffusion is a practical commercial method, which can be implemented easily in the production process at
low cost.
