graphite in the production of semiconductors carbon

The History of Carbon

Cylinder molded (man made) graphite electrodes, electric brushes, and other carbon products that were superior to foreign products were able to be manufactured. Upon entering the Showa Era (1926-1945), the carbon industry was headed for expansion along with the expansion of the ammunition industry, however, that was halted due to the damage from World War II.

Pyrolytic graphite production is based on a gaseous precursor. Pyrolytic graphite is an aggregate of graphite crystallites, which have dimensions that may reach several hundred nm. It has a turbostratic structure, usually with many warped basal planes, lattice defects, and crystallite imperfections.

Graphene

Graphene (/ ˈ ɡ r f iː n /) is an allotrope of carbon consisting of a single layer of atoms arranged in a two-dimensional honeycomb lattice. The name is a portmanteau of graphite and the suffix -ene, reflecting the fact that the graphite allotrope of carbon consists of stacked graphene layers.
