摘要

B atoms dissolve graphite lattice substitutionally up to 2.35 at. % at 2350°C. B doping causes the lattice constant a_0 to increase and the lattice constant C_0 to decrease. B-doped natural graphite shows a Raman forbidden fundamental at 1360 cm"1 due to disorder in basal plane. In the present study, highly crystallized graphite films were prepared and boron-doped. For the boron-doped graphite films, structural study was carried out by measurements of X-ray diffraction and Raman scattering.
