Graphene films synthesized by chemical vapor deposition with ethanol

概要

論文の詳細を見る
Carbon films were synthesized on a Ni substrate by a chemical vapor deposition with ethanol at 900 °C followed by a rapid cooling. From the optical microscopic images, it is found that the film is composed of uniform grains with 3～8 μm. The Raman spectra show that the grains have high degree of graphitization. In addition, it is found that some of areas in the film exhibit 1-3 layer graphene, although they are minor in the film.
