1. Graphene Semiconductors David Brown Student ECE Department University of Utah October 29, 2009

2. Overview What is graphene? Advantages of graphene Problems

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

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

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

6. Possible Uses Coating for LCD screens Computer chips Transistors Capacitors
