Abstract
By using kinetic‐energy‐resolved measurement of adsorbate fragmentation, we observe an electron‐transfer reaction from the conduction band minimum of a semiconductor surface to a molecular adsorbate. Bond cleavage in the molecular system, CH3Br on GaAs(110), occurs through a mechanism analogous to gas‐phase dissociative electron attachment.Keywords
