Graphene is an unusual single-atom thick carbon semiconductor.  (Source: i09)

Researchers measured the heat of a graphene transistor for the first time using atomic force microscopy. The results were surprising -- the material significantly self-cools.  (Source: Alex Jerez, Beckman Institute for Advanced Science and Technology)

"cost as much as $100M USD to produce a single cubic centimeter of material."

According to what wikipedia says about the distance of stacked graphene sheets, this equals about $3 per cm^2 of graphene layers. How many layers do you need?

Not sure but the $3 per cm^2 is that a R&D price or a pass production price. Just curious cause mass production is always cheaper then the R&D cost.

The thickness depends on the methods used... typically graphene is referred to as a monolayer.

The lowest thickness I have seen reported is 5.3 Angstroms... so it would take ~18.9 million of them to form a 1 cm^3 block...
