  7. 5. Temperature programmed studies of molecular assemblies on gold

    Författare :Mattias Östblom; Sven Oscarsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis investigates the properties of ultra-thin layers of organic molecules deposited at or adsorbed onto thin films of gold. The two main experimental techniques used in this thesis work are Temperature Programmed Desorption-Infrared Reflection Absorption Spectroscopy (TPD-IRAS), an excellent technique to probe the structure and orientation of molecular layers on metallic substrates, and Temperature Programmed Desorption-Mass Spectroscopy (TPD-MS), a very useful tool to study the energetics of molecular layers and adsorbates on solid surfaces.
