Abstract
Lithium-doped polymer-derived silicon carbonitride ceramics (SiCN : Li) synthesized at various pyrolysis temperatures, have been investigated by means of multifrequency and multipulse electron paramagnetic resonance (EPR) and Raman spectroscopy in order to determine different defect states that may impact the materials electronic properties. In particular, carbon- and silicon-based ‘dangling bonds’ at elevated, as well as metallic networks containing Li0 in the order of 1 μm at low pyrolysis temperatures have been observed in concentrations ranging between 1014 and 1017 spins mg−1.
