A method for preparing a graphite intercalation compound having a metal or a metal compound inserted between adjacent graphite layers, comprising simultaneously introducing a mixture of a vapor of both a hydrocarbon compound and an organo metallic compound together with a carrier gas into a reactor, and decomposing said hydrocarbon compound and said organo metallic compound on a single-crystalline substrate at a relatively low temperature.

The disclosure is directed to a method for converting between heat energy and electric energy which is characterized in that a carbon intercalation compound is employed as a thermoelectric material by utilizing a temperature difference in a direction perpendicular to the structure of carbon layers, or a method for producing a light-heat converting material which is characterized in that a thin metallic layer like a translucent mirror is caused to adhere to the inner surface of a light transmissive hollow tube by pyrolytically decomposing at a temperature approximately below 1000.degree. C., with hydrocarbons being introduced into the hollow tube at the rate of a predetermined amount per hour.

Materials for thermoelectric and light-heat conversion

A method for preparing graphite intercalation compounds having metal or metal compounds. The method consists of the simultaneous thermal decomposition of two kinds of starting materials by a CVD (Chemical Vapor Deposition) method in which hydrocarbon as a source material for the host graphite and other organometal reagents or metal halides for guest metal species or metal compound are decomposed simultaneously in a reactor in order to intercalate the metal species or metal compound into carbon being deposited on the substrate.

A method for preparing pyrolytic carbon film having a highly ordered graphite structure which comprises introducing an aromatic compound not having a condensed ring, together with a carrier gas into a reaction chamber, thermally decomposing the aromatic compound at a temperature up to 1,000.degree. C., and depositing the carbon film onto a single-crystalline substrate.
