The relation between chromia scale spallation during oxidation or cooling down of ferritic stainless steels is generally discussed in terms of mechanical stresses induced by volume changes or differential thermal expansion. In the present paper, grow

The evolution of stress in diamond layers is investigated both experimentally and theoretically in order to develop a comprehensive view of the formation of residual stress. A compressive stress maximum associated with grain coalescence, a decreasing

Vickers microindentations obtained with loads between 0.05 N and 2 N were performed on crystalline (100) silicon. The residual stress field and the different structural states induced by loading were studied by mapping the indented zones by their mic

The changes in the Raman spectrum of thin films of C60 deposited on β-alumina substrates were investigated as a function of temperature and of laser power in micro and macro Raman configuration. A large decrease in the Ag modes intensity is observed

Heavily B‐doped polycrystalline diamond films ([B]≳1019 cm−3) are studied by Raman spectroscopy and electron spin resonance. The formation of an impurity band is accompanied by a Fano‐type interference for the one‐phonon scattering. Bands a

After a brief report of recent WSi2 Raman results on the band assignment and thermal behavior of the WSi2 lines obtained for both a single crystal and a thin film, a calculation of vibrational frequencies and normal coordinates at the zone center is

Textured diamond films prepared by CVD were studied by X-ray measurements and Raman spectroscopy in the high dispersive mode in order to get structural information. A 〈100〉 fibre texture is observed for the films prepared with a 2% methane concen
