F3-A (maj 31 2002), E3-A (dec 15 2001) |
| Recommended semester: 7th - 9th semester |
| Scope and form: Lectures, laboratory exercises and oral presentations. |
| Evaluation: Oral exam and approval of reports
|
| Examination: 13-scale |
| Previous course: 10229, 10462 |
| Prerequisites: 10300 / 10203 (simultaneously) |
| Aim: To give the students knowledge of the atomic-scale physics available at the interface between solid and gas / liquid phases. This is of fundamental importance if you want to understand technologically important processes, e.g. catalysis, adhesion, tribology, and mechanical and chemical properties of new nanomaterials. The course aims at giving the students an overview of the most applied methods and an introduction to how these can be used to study realistic problems within the surface physics area. The student will during the course independently perform experiments on advanced equipment, such that hands-on experience with some of the methods is acquired. An important part of this course is the combination of experiments, report-writing, and oral presentations in order to give the students experience with evaluating the individual methods for solving specific problems and to read the relevant literature. |
| Contents: Quantum mechanical description of the physics and chemistry of clean surfaces, including the electronic and structural properties. Description of electron structure of adsorbates of the surface, phase transitions in two dimensions, epitaxy, adsorption / desorption mechanisms, chemisorption and the dynamics of chemical and physical reactions. Description of the prerequisite for experimental studies of these surfaces under well-defined conditions - this is ultra-high vacuum (UHV) with base pressures below 1e-13 bar. The most popular methods, e.g. x-ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), ion scattering spectroscopy (ISS), low energy electron diffraction (LEED), electron microscopy (EM) og scanning probe microscopy (AFM and STM) will also be described. Furthermore, fundamental aspects of heterogeneous catalysis will be analysed. All the above-mentioned methods will be discussed by use of a combination of lectures, exciting new research and application papers, and experiments followed by reports and oral presentations. |
