Surface resistivity of hydrogenated amorphous carbon films: Existence of intrinsic graphene on its surface
Savcho Tinchev
Surface resistivity of hydrogenated amorphous carbon films was measured as a function of the applied electrical field. The measured dependence shows a sharp ambipolar peak near zer…
Low temperature crystallization of diamond-like carbon films to graphene by low energy plasma surface treatment
Savcho Tinchev
Plasma surface modification was used to fabricate graphene on the top of insulating diamond-like carbon films. It is shown that by a combination of pulsed argon plasma treatment an…
Interference effects on the ID/IG ratio of the Raman spectra of diamond-like carbon thin films
Elitza Petrova, Savcho Tinchev, Petranka Nikolova
Ratio of the intensity of D- Raman peak and G- Raman peak (ID/IG) is often used for characterization of diamond-like carbon films, for example to estimate number and size of the sp…
Single electron tunneling as a possible conduction mechanism in diamond like carbon film
S. S. Tinchev, S. Alexandrova, E. Valcheva
Nonlinear current voltage characteristics and in some cases also step like characteristics were observed in diamond like carbon films. We suggest that the transport mechanism is tu…
