Roger Uhrberg 091020

TFYA25 Physics of Condensed Matter, part II

Literature: C. Kittel , Introduction to Solid State Physics, 8th edition.

A collection of problems and some lecture notes will be handed out at one of the first lectures.

Course content:

The course gives a fundamental description of how electronic structure and lattice vibrations give rise to magnetism, superconductivity and optical properties of materials and describes how these phenomena can be used. The lectures will be given in English.

Each student should give a 15 min. oral presentation in English on a topic related to the course. The teaching will be a mixture of lectures and problem solving sessions. Besides the mandatory oral presentation there will be a written examination with six problems/questions.

Oral presentation

The oral presentation is a compulsory part of the course TFYA25. Each student should give a 15 min. presentation in English on a topic that is related to the course. The presentation is done in front of a smaller subgroup of typically five other students. Each student should listen to the presentations of the other students in his/her subgroup.

The presentation should be done using Power Point.

Below, there are several examples topics from previous years. The topic should be related to the material discussed in the course.

When you have selected a topic you should tell me so that I can make a note of it. The topics will be distributed on a first come, first served, basis. This is an individual assignment and each student should therefore present a topic different from those of the other students. On the billboard labeled “Lab-anmälan” near “IFM’s kursexpedition” you can sign up for a suitable time for the presentation.

Some examples of topics

1. Superconducting devices: Example, SQUID

2. The Josephson effect, one-electron tunneling.

  1. High temperature superconductors: Theoretical models, material properties, crystal structure, electronic structure.

4. In connection to superconductivity strong magnetic fields are often mentioned. How can they be realized?

5. Research about thin magnetic films. What is being done? What are the goals?

6. Heisenberg theory of ferromagnetism. The exchange integral.

7. Giant magneto resistance.

8. Fullerenes/nanotubes: Superconducting properties and other material properties.

9. Porous silicon emits blue light. What is the status of the present research? What is the mechanism for light emission?

10. Studies of solid materials using synchrotron light:

X-ray holography

X-ray diffraction, surface x-ray diffraction

X-ray fluorescence

XAFS (X-ray Absorption Fine Structure)

11. Scanning tunneling microscopy, atomic force microscopy.

12. How does a solid fracture on an atomic scale? What is the role of defects and dislocations?

13. Surface electronic structure from an experimental and/or a theoretical perspective.

14.Low energy electron diffraction (LEED). Determination of the surface atomic structure.

  1. Electron energy loss spectroscopy.
  1. Applications of high temperature superconductors.
  1. Surface plasmons. Theory and/or applications.
  1. Jahn-Teller distortion.
  1. Luminescence.
  1. Raman spectroscopy.
  1. New high temperature superconductors.
  1. Nuclear magnetic imaging.
  1. Magnetic storage media.
  1. Optical storage media.
  1. Neutron magnetic scattering.
  1. Scanning tunneling spectroscopy.
  1. Semiconductor or solid state lasers.
  1. Semiconductor solar cells
  1. Spin-polarized photoelectron spectroscopy.
  1. Magnetic force microscopy.
  1. Spintronics
  1. New materials: SiC, GaN, …..
  1. Quasicrystals.
  1. Piezoelectric materials.

A good start is to find a review paper on the subject where one can usually find references to important papers. Select a few that are suitable to base a presentation on. For some of the above examples you may find review articles in Physics Today or Physics World. Other journals that could be of interest are Nature and Science.
