This paper reports the formation and properties of hydrogenated amorphous carbon (a-C: H) films having embedded
nanoparticles deposited by cathodic jet carbon arc (CJCA) technique in absence of magnetic field. The films have been
characterized by XRD, HRTEM, XPS, dark conductivity, activation energy, optical band gap, residual stress, hardness,
elastic modulus and plastic index parameter. The properties evaluated of a-C: H films having embedded particles have
been compared with that of undoped and nitrogen doped a-C films having embedded nanoparticles deposited by CJCA
technique. All the properties of a- C films studied are found to depend on the gaseous environment used during the
deposition of the films. These a-C films having embedded nanoparticles act as hard coating materials.
