Single Crystal Diamond Films

Diamond films are important for radiation tolerent devices. However, fabrication of single crystal films has proven to be much more difficult than polycrystalline deposits. A novel deposition process is proposed which can be used to deposit diamond on a seed crystal. The technique permits patterned deposits in island and offers the potential of a new method for attempting to dope diamond semiconductors. Diamond films offer the highest radiation resistance of any semiconductor material and are thus important for military and space applications. The problems of fabrication of single crystal diamond films have not yet been solved. If this work is successful, a major materials limitation will have been resolved.
