# Wave function of graphene

## Main Question or Discussion Point

I have read many papers stating that the wave function of graphene has two components due to the fact that the unit cell of graphene consists of two carbon atoms (A and B atoms). However, I was confused about that. If the unit cell consist of more atoms, what will the wave function be? Does it has more component?
Do not deride me for my stupied question for I'm not majored in theory. Expecting someone's instruction.
