Kenntnisse |
(*)Upon completing the course, students will possess the following skills. They are able to
- execute experiments for surface characterization, such as an ellipsometer or scanning tunneling microscope (STM), and optimize measurement parameters (k2/k3);
- collect and analyze data, using advanced software to interpret experimental data with the help of theoretical models (k4);
- refine parameters for fit accuracy, assess sources of error (e.g., surface roughness, model assumptions) and discuss the validity of results (k4/k5);
- apply critical thinking and problem-solving to troubleshoot experimental challenges and refine methodologies (k5);
- communicate scientific findings effectively through data interpretation, discussion and presentation of results (k4/k5).
|
(*)During the course, students will acquire practical knowledge in the experimental characterization of surfaces and thin films. Different experiments, ellipsometry or scanning tunnelling microscopy (STM), will be offered. The topic will be announced at the beginning of each semester.
ellipsometry:
- measurement principle for thin film characterization;
- dielectric function and film thickness analysis;
- application of optical models to real-world material systems.
STM:
- tunneling effect and its application in STM;
- fundamental principles of STM, including quantum tunneling, tip-sample interactions, data acquisition techniques, atomic resolution imaging;
- correlation between surface lattice structure and surface atomic structure;
- role of STM in advancing nanotechnology and materials science.

| Beurteilungskriterien |
(*)The final grade is determined in a comprehensive evaluation process that assesses both theoretical understanding and practical skills. The evaluation consists of the discussion in the briefing meeting (10%), the performance in the lab (20%), a report (40%) and a final oral exam (30%).

| Lehrmethoden |
(*)Students will conduct experiments in groups of two.
