Carbon diffuses into metal and recrystallizes as graphite, which is termed graphitization of carbon by metal. This study has revealed that the temperature at which this graphitization occurs depends on the initial state of the carbon. The lowest temp

Islands of highly oriented graphite were grown by chemical vapor deposition at 900 °C upon a Pt film with initial thickness 50 nm formed on sapphire. The value of mosaic spread estimated from a rocking curve for graphite (002) X-ray diffraction was

Thin film formation of graphite by chemical vapor deposition using 2-methyl-1,2′-naphthyl ketone as a starting material was carried out on Ni film substrates. On Ni films directly deposited on quartz glass, the graphite films were obtained when the

Graphite thin films can be formed by CVD on Ni films with a thickness of 500 A deposited on sapphire (110), (001) and (012) faces. The c-axis of the graphite film deposited on Ni/sapphire (110) is almost perpendicular to the sapphire surface. However

Two functions of Ni in the process of graphite thin‐film formation from organic materials by chemical vapor deposition (CVD) were studied. When dehydrogenation of a certain organic material was enhanced by Ni during CVD at 600 and 700 °C, the grap

A nucleation model was proposed for a carbon nanotube enclosing a Ni bar which was grown by chemical vapor deposition (CVD) at 700 °C using round Ni particles. At an early stage of CVD, each round Ni particle with a diameter of about 30 nm is covere
