Point( ECTS )
Taught under open university
|General competence course, MSc. Eng., Physics and Nanotechnology |
Technological specialization course, MSc. Eng., Physics and Nanotechnology
Technological specialization course, MSc. Eng., Sustainable Energy
Scope and form:
|Lectures, laboratory exercises and oral
Duration of Course:
Type of assessment:
|Minimum 6 Maximum: 30|
General course objectives:
To give the students knowledge of the atomic-scale physics
prevailing 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.
A student who has met the objectives of the course will be able to:
- Explain phenomena which are responsible for the structure and
composition of surfaces.
- Explain the physical phenomena which are responsible for
adsorption on surfaces.
- Explain general tendencies in surface reactivity and surface
- Determine nanoparticle structure and stability under vacuum and
in reactive atmospheres.
- Analyze catalytic processes by simple models.
- Explain the most important catalytical processes and describe
the most significant technical obstacles.
- Explain how nanoparticles in the future may provide solutions
for future energy production.
- Explain in detail the principles of methods for surface
analysis, and why they are surface sensitive.
- Determine which method is most appropriate for a certain
problem like for example determining the surface composition.
- Perform a critical and comparative evaluation of results
obtained with various surface sensitive methods.
- Evaluate the different methods on the obtainable results, time,
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,
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 10E-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) and scanning probe
microscopy (AFM and STM) will also be described. Furthermore,
fundamental aspects of heterogeneous catalysis especially in
connection with the future energy production 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.
A visit to the industry is also enclosed.
