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
