Course introduction
The course is divided into two parts: The first part focuses on an introduction into modern surface science techniques, with emphasis on kinetics and dynamics of reactions on surfaces, catalysis, gas-surface reactions, film growth, and surface morphology. It deals with both experimental and theoretical methods and approaches. The second part gives an introduction to the chemical synthesis and analysis of advanced ceramic materials, including amorphous and mesoporous materials.

Subject overview
Part 1: Surface technology

Part 1 includes the scientific background for surface technology, in the form of experimental surface science and the basic concepts of Ultra High Vacuum technology. In the course some of the following topics will be covered, based on the interest and background of the participants (with demonstrations in the labs.):

Electron spectroscopies and diffraction techniques; electron microscopy and spectroscopic microscopies; scanning probe techniques; gas-surface interactions: adsorbate binding and kinetics, theoretical concepts; reactions at surfaces: kinetics and dynamics, recent experimental developments (laser desorption techniques); femto-second laser studies of adsorbate systems; surface states; electronic and phononic surface excitations; rough surfaces.

Part 2: Chemical synthesis and characterization of advanced ceramic materials.

Preparation of sintered ceramic pellets, single crystals and amorphous materials; characterization by powder X-ray diffraction and solid state NMR spectroscopy; order-disorder phase transitions; relation between structure and electrical, magnetic and optical properties.

(a). The synthesis, structural and electrical characterization of CuZr2(PO4)3 (Cusicon).

The preparation of sintered ceramic pellets of the copper(I) fast ionic conductor CuZr2(PO4)3 by high-temperature solid-state reaction methods. Structural characterization of the product material by powder X-ray diffractometry (XRD), single crystal diffractometry and solid state NMR.

Characterization of dynamic properties by solid state NMR.

Electrical characterization by electrochemical impedance spectroscopy (EIS) as a function of temperature and oxygen fugacity. Determination of EMF for a copper activity cell, such as, for example: CuO  CuZr2(PO4)3  CuAl2O4, Al2O3 in air (PO2 = 0.21 atm) between 5001000 °C.

Crystal structure and electrical properties are then related and discussed.

(b). The above exercise studied on analogue materials, such as; CuTi2(PO4)3, CuSn2(PO4)3 and CuNbSc(PO4)3, as well as, other electrode systems for the EMF measurements.

Students work in groups of 2-3 (depending on numbers). Each group submits a joint written report and gives an oral presentation of their work to the class.
