Learning Outcome

After successful completion of the module the students are able to:

  •  understand and describe several surface science concepts and techniques, including 2D-crystallography, elemental and chemical analysis at surfaces, electronic, vibrational and magnetic properties of surfaces, adsorbate bond formation, surface dynamical processes like diffusion, adsorption and desorption, and surface chemical reactions in heterogenous catalysis
  • identify the different kinds of nanoscale objects and nanostructured surfaces and discuss:
    1. their properties,
    2. their underlying fabrication schemes (including top-down and bottom-up approaches with emphasis on self-assembly & self-organized growth processes) and
    3. examples of their application in chemistry (catalysis) and electronics/spintronics.

Preconditions

While there are no strict requirements, previous exposure to quantum mechanics and thermal physics and the basic notions of atomic, molecular & condensed matter physics will be helpful.

Courses, Learning and Teaching Methods and Literature

Courses and Schedule

Learning and Teaching Methods

This module consists of a lecture and exercise classes. The lectures are thematically structured and a detailed script is given at the beginning of each lecture. Each lecture commences with a clear outline of the learning objectives. Concepts are linked to prior knowledge acquired both in the general course of study and within the topics covered in this module. The beamer is used for the lecture presentation, while important concepts are illustrated and highlighted on the blackboard. 

The exercise classes provide a deeper understanding through examples and case studies from the scientific literature. They are further a setting for stimulating scientific discussions and where the students are encouraged to present and put into context their learning outcome. Laboratory visits guided by experts enhance the insight in the current applications of surface and nanoscale science. 

Question sheets provide the means of self-evaluation. Handouts and course announcements are also communicated via the Moodle platform. 

Media

Module Exam

Description of exams and course work

There will be an oral exam of 25 minutes duration. Therein the achievement of the competencies given in section learning outcome is tested exemplarily at least to the given cognition level using comprehension questions and sample calculations.

For example an assignment in the exam might be:

  • Describe chemisorption: the energy potential, the bond strength, the bond characteristics and give an example.
  • How are surface reconstructions and overlayer structures described?
  • Draw the energy diagram for a possible electron (de-)excitation within an atom.
  • Draw the Ewald sphere for a 3D crystal and a 2D crystal. What are the conditions for diffraction?

Participation in the exercise classes is strongly recommended since the exercises prepare for the problems of the exam and rehearse the specific competencies.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
