Journal ArticleDOI
Characterization of heavily B‐doped polycrystalline diamond films using Raman spectroscopy and electron spin resonance
TL;DR: In this paper, the formation of an impurity band is accompanied by a Fano-type interference for the one-phonon scattering, which is related to maxima in the phonon density of states, and are ascribed to disordered regions or crystalline regions of very small size.
Journal ArticleDOI
Electrical conduction and deep levels in polycrystalline diamond films
TL;DR: In this paper, the authors studied the dark conductivity (field, temperature, and frequency dependence) and the photoconductivity in undoped polycrystalline diamond films and showed that either of two alternative models can be invoked to explain all the observed features of the light conductivity.
Journal ArticleDOI
Chemical vapor deposition of B‐doped polycrystalline diamond films: Growth rate and incorporation efficiency of dopants
Patrice Gonon,Alain Deneuville,F. Fontaine,Etienne Gheeraert,A. Campargue,M. Chenevier,S. Rodolphe +6 more
TL;DR: In this article, the growth rate and incorporation efficiency of dopants have been studied in the case of chemical vapor deposition of B-doped polycrystalline diamond films, and the deposition rate is found to decrease with the addition of diborane in the gas phase.
Journal ArticleDOI
Conduction mechanisms in boron implanted diamond films
TL;DR: In this article, the relationship between variable range hopping (VRH) below 300 K and the defects created during boron ion implantation at 77 K in as-implanted diamond films and films annealed at 800 °C was investigated with the help of electron spin resonance (ESR) and optical measurements.
Journal ArticleDOI
Reality of doping by boron implantation of CVD polycrystalline diamond from a comparison of Raman and electrical measurements
TL;DR: In this article, the effect of boron doping on polycrystalline CVD diamond was studied by Raman scattering and I(V, T) measurements and the amorphization threshold was found to be located around a 3 × 10 15 cm −2 doping.
