Re. Treece et al., PULSED-LASER ABLATION SYNTHESIS OF NBNX LESS-THAN-OR-EQUAL-TO-X-LESS-THAN-OR-EQUAL-TO-1.3) THIN-FILMS, Chemistry of materials, 6(12), 1994, pp. 2205-2207
Reactive pulsed laser deposition has been used to control the composit
ion and phase of niobium nitride (NbN(x)) films deposited from a Nb ta
rget in a N2 (90%)/H2 (10%) atmosphere onto MgO (100) substrates. The
nitrogen content of the NbN(x) (0 less-than-or-equal-to x less-than-or
-equal-to 1.3) films increased with gas pressure. The assignments of t
he single-phase films of oriented Nb, Nb2N, NbN, and Nb3N4 were based
on X-ray diffraction, Rutherford backscattering spectroscopy, and temp
erature-dependent resistivity measurements.
