Electron spin resonance study of hydrogen-free germanium-doped diamond-like carbon films
Original language description
Hydrogen-free germanium (Ge)-doped diamond-like carbon (DLC) films deposited on SiO2 substrates are studied by electron spin resonance (ESR) technique at T ¼ 5–295 K. The Ge-free and DLC films with 1 and 2.5 at% Ge content having low cytotoxicity are investigated. A single Lorentzian ESR line resulting from exchange interaction between localized (LE) and nonlocalized electrons (NE) is observed. The spin susceptibility temperature dependence deviates from the Curie–Weiss law at T >75 K due to Pauli contribution caused by NE. The antiferromagnetic lowtemperature spin ordering in DLC films, decreasing with Ge content, is observed. The LE contribution is significant for Ge-free and DLC:1%Ge, whereas NE makes the main contribution to DLC:2.5%Ge. The LEs are related to sp2/sp carbon-related centers, while the NEs are assigned with electrons in the sp3 orbital. The correlation between the sp3/sp2 ratio and the shift of g-factor for NE to lower values with Ge doping is established.n
