Abstract

Epitaxial films of TiC1-x (0.15 < x < 0.50) were deposited on MgO(001) and 6H–SiC(0001) at 250 and 400 °C by coevaporation of C60 and Ti. Films deposited on MgO(001) were single-crystalline down to deposition temperatures of at least 250 °C as determined by x-`ray diffraction (XRD), low energy electron diffraction (LEED), and transmission electron microscopy (TEM). Films deposited on 6H–SiC(0001) were also epitaxial at 250 °C, but TEM showed a columnar microstructure due to the occurrence of twinned domains in the [111] growth direction normal to the substrate.
