▎ 摘 要
A few-layer graphene-based hybrid material with high thermal and chemical stability and reproducible and tunable electronic properties was fabricated by intercalation of N-methylpyrrolidone into a few-layer graphene combined with heat treatment. Depending on the process temperature, the obtained material could be produced with the following properties: a broad range of resistivity values (six to seven orders of magnitude) in combination with a high carrier mobility, a tunable band-gap (from 0 up to 3-4 eV) and sp(2) or sp(3) hybridization of carbon atoms. The extremely strong step-like temperature dependence (within 10 degrees C) of its properties observed in the vicinity of two temperatures, 90 and 200 degrees C, seems to be important for various applications. The hybrid material opens viable routes to progress in the design of three-dimensional nanostructures.
