LEEM investigation of the initial growth of hetero-organic layers — •Caroline Henneke, Benjamin Stadtmüller, Thomas Duden, and Christian Kumpf — Peter Grünberg Institut (PGI-3), Forschungszentrum Jülich, 52425 Jülich, Germany, and Jülich Aachen Reseach Alliance (JARA)-Fundamentals of Future Information Technology

One crucial issue for the success of organic materials in electronic devices is the ability to specifically design the interfaces between different active layers according to their functional purpose. The initial growth, i.e., the formation of the first molecular layer, is of particular interest in this context as this layer acts as a template for further growth.

We recently started to investigated hetero-organic layers consisting of Copper-II-phthalocyanine (CuPc) and 3,4,9,10-perylen-tetracarboxylic-acid dianhydride (PTCDA) on Ag(111). Using LEEM/PEEM, LEED and STM, we have identified three mixed phases with different stoichiometry. Kinetic processes like thin film growth, the formation of the organic mixed layer, and the transition between different phases were studied in real time with LEEM. The lateral structure of the different phases was investigated with SPA-LEED and STM.
