- - METHOD FOR MANUFACTURING ROD-LIKE CARBON-GERMANIUM COMPOSITE AND ROD-LIKE CARBON-GERMANIUM COMPOSITE

摘要

The present invention relates to a method to manufacture a rod-like carbon-germanium composite, capable of simplifying an existing manufacturing method, and a rod-like carbon-germanium composite thereof. According to the present invention, the method comprises: a step of preparing a reaction tank including a cathode and an anode having a base material receiving part; a step of filling the base material receiving part with a germanium base material; a step of filling the reaction tank with a raw material gas including a carbon-controlling gas; and a step of performing arc discharge in the reaction tank to manufacture a rod-like carbon-germanium composite. A ratio of the pressure of the carbon-containing gas in the reaction tank with respect to the pressure of the raw material gas in the reaction tank is equal to or greater than 0.01 and equal to or less than 0.1, and the rod-like carbon-germanium composite includes a carbon layer on a surface of a rod-like germanium core.
