Research

Andreas is investigating the charge transfer and valence change mechanisms that lead to resistance switchig in transition-metal oxides for non-volatile memory application.
The focus of his work lies on the observation of ion and electron motion and the resulting changing conductivity during the switching process in model switching cells.
