WebThe structure of the crystal has a cubic elementary cell, looking like a “ Giant molecule.” Graphite, on the other hand is made up of many carbon ring layers (graphene – see later) stacked together, with the elementary cell being of hexagonal type. Unlike diamond, graphite has zero bandgap, which conducts heat and electricity very well.
