Abstract

The results of an investigation of the growth and physical properties of epitaxial single-crystalline NaCl-strucute Ti_1-xW_xN alloys are presented. X-ray diffraction (XRD), transmission electron microscopy (TEM), and XTEM analysis show that Ti_0.5W_0.5N(001) alloys exhibit long-range CuPt ordering on the cation sublattice. It was found that the superconducting critical temperature T_c initially increases with x, reaches a maximum of 6.67 K at x=0.21, and decreases at larger x values.
