Latest Patents
Graham's latest patents include innovative methods for the manufacture of cadmium mercury telluride. The first patent details a method involving the growth of buffer layers on a substrate using molecular beam epitaxy (MBE). This process allows for the subsequent growth of cadmium mercury telluride layers by metal organic vapor phase epitaxy (MOVPE). The use of MBE for buffer layers ensures the correct orientation for MOVPE growth and prevents contamination during the process. The invention also encompasses new devices formed through this method.
The second patent focuses on the manufacture of cadmium mercury telluride on patterned silicon. This method allows for the growth of CMT on silicon substrates that bear integrated circuitry. By defining growth windows through masking, Graham's technique enables crystalline growth within these windows while allowing for the removal of polycrystalline growth outside of them. This innovation eliminates the need for hybridization, streamlining the manufacturing process.
