Overview What is graphene? Advantages of graphene Problems

Graphene Sheet of pure carbon rings one atom thick Made by peeling layers from graphite [1]

Advantages of Graphene Conducts electrons 100 times easier than silicon Two dimensional Easier to control electron flow Allows for smaller devices [2]

Problems Not easily produced Does not switch like other semiconductors Just beginning to be studied [3]

Possible Uses Coating for LCD screens Computer chips Transistors Capacitors
