Responsible coordinator of the module PH2218 is Winfried Petry.
Content, Learning Outcome and Preconditions
This module is concerned with the arrangement and movement of atoms in solids. As these aspects determine to a large part the macroscopic properties of matter, their microscopical understanding is fundamental to, e.g., the tuning of materials for technological applications.
Going beyond the coverage of the previous semesters' Solid State Physics course, the following topics will be treated in detail:
- the arrangement of atoms in a solid -- crystal structures and symmetries, alloys and ordered compounds, statistical models and phase diagrams
- deviations from this ideal arrangement -- point defects, dislocations, grain boundaries, surfaces
- oscillations of atoms about their equilibrium positions -- phonons
In the following summer term, the second part of the course will concern itself with
- atoms exchanging places -- diffusive dynamics, jump mechanisms in elemental systems and ordered compounds, mass flux
- break-down of long-range order -- glasses, melts, and their dynamics
- transitions between different states of order -- dynamics and kinetics of phase transitions
For all the above points it is intended to give both a description of the physically observed phenomena and their motivation by microscopic models. Also, the relevant experimental techniques will be indicated and explained in principle, and, where applicable, simple computer models of the effects will be presented and provided to the students for tinkering with.
Upon successful completion of the module, students are able to
- list the main crystal structures and analyze them with respect to their symmetries
- discuss qualitative features of interactions between atoms and their relation to the resulting atomic arrangements
- use the concepts of reciprocal space
- derive models for free energy and solve them to determine defect concentrations and qualitative phase diagrams
- understand the concept of phonons, their branches and symmetries over reciprocal space, densities of states and anharmonic effects
- propose and justify experimental and/or theoretical methods to elucidate simple problems of atomic-scale materials science
No preconditions exceeding the admission requirements for the master degree program.

Description of exams and course work
In an oral exam the learning outcome is tested using comprehension questions and sample problems.
Remarks on associated module exams
The exam for this module can be taken together with the exam to the associated follow-up module PH2219: Materialphysik auf atomarer Skala 2 / Materials Physics on an Atomistic Scale 2 after the follwoing semester. In this case you need to register for both exams in the following semester.
There is a possibility to take the exam at the end of the semester. There is a possibility to take the exam in the following semester.
