2D molecular systems at surfaces
 Kormoš, Lukáš ; Mysliveček,, Josef (oponent) ; Schlickum, Uta (oponent) ; Čechal, Jan (vedoucí práce)
Molecular systems represent one direction of the current research in novel nano-electronic devices. Organic molecules are considered in various applications such as solar cells, displays or quantum computing. Growth of high-quality molecular layers with desired properties often employs self-assembled structures and requires a deep understanding of metal-organic interface and dynamics of the molecular layer growth. Work presented in the thesis is in the beginning focused on self-assembly of biphenyl-dicarboxylic acid (BDA) on Cu (1 0 0) and Ag (1 0 0) studied in UHV utilizing STM, XPS and LEEM. In the case of BDA/Ag, multiple chemically and structurally distinct molecular phases are described in detail. Next, the BDA and TCNQ self-assembly is studied on graphene grown on Ir (1 1 1). In addition, metal-organic systems were synthesized by deposition of additional Ni and Fe atoms with TCNQ and BDA molecules on graphene. The nal part of this work presents on-surface synthesis of graphene nanoribbons (7-AGNR) on kinked Au (16 14 15) substrate from DBBA precursor molecules. Surface reconstruction after growth is analysed by STM and electronic properties of 7-AGNRs by ARPES.
