Nanostructured molybdenum carbide thin films obtained by femtosecond pulsed laser deposition

Abstract

Abstract The films obtained by ultra‐short pulsed laser deposition of a target of molybdenum carbide, at different substrate temperatures, have been characterized by different techniques, including scanning electron microscopy, micro‐Raman spectroscopy and X‐ray photoelectron spectroscopy. The results indicate that the films are formed by a large number of particles with nanomentric dimensions and are composed mainly of Mo 2 C. The presence of an excess of carbon, found in the films, is probably due the presence of a certain amount of graphite in the target (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
