TFYA20, Surface Physics

The purpose of this course is to provide the participants some insight into a current research field. Characterizations of clean surfaces of solids is a main topic of the course.
For characterizing a material a determination of both the chemical composition and the atomic structure (in the first few atomic layers) are often required and methods to do this will be presented. Sometimes the surface electronic properties such as work function and surface electronic states are of primary interest, and this will also be treated.
The other main topic of the course is effects induced upon adsorption of foreign atoms/molecules and examples of characterizations of such surfaces.

Litterature

Physics at Surfaces, by Andrew Zangwill (ALAB), plus additional reprints (that will be distributed during the course).
The content of chap. 2, 3, 4, 5, (6), 7, 8, 9, 10 and  12 in Zangwilleís book will be treated (although some parts will be omitted).

Extent

32 h lectures and 2x5h laboratory work.

Laboratory assignments

The laboratory exercises are meant to show the  merits and limitations of some experimental methods used for determining the electronic- and the atomic-structure and also the surface topography. The methods that will be treated are:  low energy electron diffraction, angle resolved photoemission and scanning tunneling microspy (or atomic force microscopy).

Examination

A written examination  for grades (5,4,3 andFail) or an oral examination for pass/fail (3/Fail). The ECTS grades wil of course also be used when required.

Additional information

In order to provide a better definition of the content of the course rehearsal questions will be handed out.
These reharsal questions and also some lecture notes will be available to download.
