We have synthesized thin films of (Ti{sub 1-x}Nb{sub x}){sub 2}AlC by combinatorial method on TiC (111) seed layers grown on c-axis sapphire (Al{sub 2}O{sub 3}) substrates at 900 deg. C using magnetron sputter. X-ray diffraction showed the films to be c-axis oriented and epitaxial, and films contained a minor secondary phase of (Ti,Nb)C, irrespective of stoichiometry. Most notably, Raman spectroscopy suggest a sizable increase in the elastic modulus in the Nb-rich region as compared to either of the end members.
