Novel effect of plasma-surface interaction discovered


A new mechanism of the interaction of ions with strongly correlated finite graphene-type fragments has been obtained: ions of certain energies create doublons in the target material. The results could allow to reversibly change the electronic properties of the material with potential applications for low-temperature plasmas. The results are published in:
