Content, Learning Outcome and Preconditions

Content

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 an introductory Solid State Physics course of Bachelor level, 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. In the following summer term the second part of the lecture will treat the dynamics of atoms in solids, that is, oscillatory (phonons) and diffusive dynamics, and their relevance for materials physics.

A continuation of the modul is PH2219 in the following semester.

Learning Outcome

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 modul 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.

Preconditions

No preconditions exceeding the admission requirements for the master degree program.

Module Exam

Description of exams and course work

There will be an oral exam of about 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.

Exam Repetition

The exam may be repeated at the end of the semester. There is a possibility to take the exam in the following semester.
