Quand le graphite devient un semi-conducteur
Le graphite est un empilement de feuillets de graphène. Les liaisons entre les atomes de carbone à l'intérieur des feuillets sont 50 fois plus fortes que celles entre les feuillets.

Mining techniques for graphite depend on the type of deposit. Flaky graphite is typically mined using open-pit methods, while amorphous graphite is often extracted using underground mining. The mining process involves drilling, blasting, and hauling the ore to a plant for beneficiation. Subsequent purification processes separate graphite flakes ...
Graphite is simply carbon — like a diamond but far softer, because of its different crystal structure. Graphite is used as a lubricant, in industrial steelmaking, for brake linings in automobiles and as pencil lead. It's also a key component of the high-powered lithium batteries that propel electric cars.
