We have studied the radiation damage in diamond as a function of layer depth upon self-ion implantation with 9-MeV carbon ions and its recovery after annealing at $1000^\circ$C. Raman and photoluminescence spectra show substantial damage of the …
We have studied the near-surface damage in a diamond crystal caused by irradiation with swift boron ions and its healing after high-temperature annealing. A diamond crystal was irradiated with 9-MeV $^{11}$B$^{3+}$ ions with fluence values between $1 …
The chlorination of ferrocene at 900°C yields very interesting carbon hollow nanospheres (CHNSs) with diameters of ∼50−150 nm and ∼12−25 nm thick walls. X-ray energy-dispersive spectroscopy shows no traces of chlorine or iron and the π*/σ* ratio of …
In the present work, $a$-C:H films have been grown from argon/methane gas mixtures by Electron Cyclotron Resonance Chemical Vapour Deposition (ECRCVD). The effect of the application of a dc bias voltage to the silicon substrate material on the …
HiPco single-walled carbon nanotubes (SWNTs) have been sidewall-functionalized with phthalocyanine addends following two different approaches: a straightforward Prato reaction with $N$-octylglycine and a formyl-containing phthalocyanine, and a …
The dielectric properties of CVD diamond films grown by the oxyacetylene flame method for frequency dependent electrical fields have been studied. The dependence of these properties on temperature (from room temperature to 150°C) has also been …
