Is graphene a semiconductor?
How do semiconductors differ from conductors and insulators?
Conductors, such as metals, have a large number of free electrons that can move easily through the material, allowing for high electrical conductivity. Insulators, on the other hand, have very few free electrons and a large bandgap, making them poor conductors of electricity. Semiconductors have a bandgap that falls between that of conductors and insulators, allowing them to conduct electricity under certain conditions.
