摘要

Recently, tetramantane, a member of diamondoid series (C_(4n+6)H_(4n+12)), has shown to exhibit negative-electron-affinity effect which has a potential use for efficient electron emitting devices. Here, we explore the electronic property of adamantane (C_(10)H_(16)), the smallest member of the series. We prepare adamantane films on Si(111) substrates and then study their electronic structure with photoemission spectroscopy. Photoelectron spectra of adamantane on Si(111) have shown a peak at low-kinetic energy which could be a generic property of diamondoids. The possibility of the negative-electron-affinity effect in adamantane is further discussed.
