PH2218 is a semester module in German or English language at Master’s level which is offered in winter semester.
This Module is included in the following catalogues within the study programs in physics.
- Specific catalogue of special courses for condensed matter physics
- Specific catalogue of special courses for Applied and Engineering Physics
- Complementary catalogue of special courses for nuclear, particle, and astrophysics
- Complementary catalogue of special courses for Biophysics
If not stated otherwise for export to a non-physics program the student workload is given in the following table.
Responsible coordinator of the module PH2218 in the version of WS 2020/1 was Michael Leitner.
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.
The following topics pertaining to the static arrangement of atoms in solids will be treated in detail:
- symmetries - point groups, space groups, Bravais lattices, positions within the unit cell
- crystal structures - elementary systems and compounds
- point defects
- aspects of order - short-range and long-range order
- statistics and thermodynamics - fundamental models for predicting observables from microscopic parameters
- phases and phase diagrams
For all the above points both a general description of the relevant concepts as well as a motivation by microscopic models will be given, but also a quantitative discussion of their realization in typical systems.
A continuation of the module is PH2219 in the following semester.
Upon successful completion of the module, students are able to:
- list the main crystal structures and analyze them with respect to their symmetries
- understand and predict which structure a given system will assume
- to apply the concepts relevant for describing point defects and to understand their behaviour
- to apply simple statistical and thermodynamical models
- to read phase diagrams and to deduce thermodynamic aspects, as well as to predict the phase diagrams resulting from given microscopic parameters
- to have a feeling for the typical values of the physical quantities relevant for the atomic scale, such as distances and energies, and to understand their consequences
Generally, this module intends to bring the students to a point where they can rationalize the results of theoretical or experimental investigations of pertinent aspects from the point of view of the present state of science, and thus to prepare them for original research.
No preconditions exceeding the admission requirements for the master degree program.

Learning and Teaching Methods
The module consists of a lecture. The learning content is presented by blackboard writing and verbal lecturing, with a detailed discussion of the treated phenomena. Here active contributions from the students (comprehension questions) are invited. To consolidate the content, private study of the provided lecture script is indicated.
Regarding the current coronavirus pandemic: this lecture will be conducted as on-campus lecture as long as the regulations allow again, in the meantime podcasts and sketches in addition to the lecture script will be provided.
Black board or beamer presentation. A lecture script will be provided, outlining the essential contents, but not superceding the detailed discussions given in the lecture.

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 discussions of the relevant concepts as well as typical realizations in solids.
For example an assignment in the exam might be:
- sketching and discussing of fundamental crystal structures, their symmetries, prototypical examples
- temperature dependence of point defect concentrations, explaining the concepts of formation energies and entropies
- discussing short-range order, defining the Warren-Cowley parameters
- explaining phase diagrams
In the exam no learning aids are permitted.
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.
The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
