This research program centers on the mechanisms of enhanced                mechanical strength and modulus in superlattices of the                         transition metal nitride type.  Growth, chemistry, structure, and               mechanical properties are measured as functions of the processing               variables, which include composition modulation, layer                          perfection, wavelength, and crystallographic orientation.                       Initial research is limited to the titanium nitride/vanadium-                   niobium nitride system.  Variations in lattice mismatch are                     accomplished through control of layer compositions.
