The electronic properties of the surfaces of polyethylene (PE) were studied via first-principles calculations. It was confirmed that PE has a negative electron affinity and that PE surfaces possess a surface state whose energy lies in the forbidden bulk gap.

Abstract
The electronic properties of the surfaces of polyethylene (PE) were studied via first-principles calculations. It was confirmed that PE has a negative electron affinity and that PE surfaces possess a surface state whose energy lies in the forbidden bulk gap.
