Graphene: The Next Big (But Thin) Thing

Graphene is a remarkable material, one atom thick, with superior electrical and thermal conductivity, and strength. It differs from graphite, despite being made of the same carbon atoms, due to its atomic arrangement. Graphene was discovered in 2004 using sticky tape to peel layers from graphite. Its potential applications include replacing silicon in microchips and use in touchscreens. However, producing high-quality graphene is challenging, similar to the early silicon industry, but solvable with time and investment.
