Abrupt stress induced transformation in amorphous carbon films with a highly conductive transition phase.
We demonstrate that when, and only when, the biaxial stress is increased above a critical value of 6+/-1 GPa during the growth of a carbon film at room temperature, tetrahedral amorphous carbon is formed. This confirms that the stress present during the formation of an amorphous carbon film determines its sp;{3} bonding fraction. In the vicinity of the critical stress, a highly oriented graphit...
متن کاملPulsed laser deposited tetrahedral amorphous carbon with high sp3 fractions and low optical bandgaps
Amorphous carbon films with sp3 bonded carbon fractions over 70% are deposited by pulsed laser deposition. However, the optical bandgap obtained from optical transmittance and spectroscopic ellipsometry analysis shows the values to be below 1.0 eV. A wide range of measurements such as electron energy loss spectroscopy, visible Raman, spectroscopic ellipsometry, optical transmittance, and electr...
متن کاملStress-induced formation of high-density amorphous carbon thin films
Amorphous carbon films with high sp content were deposited by magnetron sputtering and intense argon ion plating. Above a compressive stress of 13 GPa a strong increase of the density of the carbon films is observed. We explain the increase of density by a stress-induced phase transition of sp configured carbon to sp configured carbon. Preferential sputtering of the sp component in the carbon f...
متن کاملEffect of Amorphous Silica Addition on Martensitic Phase Transformation of Zirconia and Investigation of its Tetragonal Structure Stability Mechanisms
This work is focused on the effect of amorphous SiO2 addition on the phase transformation and microstructural evolution of ZrO2 particles. Considering the structural similarities between the amorphous ZrO2 and its tetragonal structure, XRD results showed initial nucleation of metastable tetragonal ZrO2 from its amorphous matrix upon heat treatment. This metastable phase is unstable in pure ZrO2...
متن کاملEvolution mechanism of nanocrystalline tungsten-carbon and effects on tungsten implanted amorphous hydrogenated carbon
Tungsten doped amorphous carbon films are prepared on silicon 100 by postimplantation of tungsten ions into pure amorphous hydrogenated carbon using the plasma immersion ion implantation technique. The peak concentration of tungsten reaches 27 at. % and W–C nanocrystallites with largest diameters of 5 nm are formed in the near surface region. Both the quantity and size of these nanocrystallites...
