 | There are a number of special modules that you should use for navigating through
the Hyperscript: |
|  | Detailed table of contents of the main part (called
"backbone") |
| | Matrix of Modules; showing all modules in context. This
is your most important "Metafile"!!! |
| | Indexlist; with direct links to the
words as they appear in the modules. All words contained in the indexlist are marked black and bold in the
text. |
| | List of names; with direct links to the words as they appear in the modules. All
names contained in the name list are marked red and bold in the text. |
| | List of abbreviations; with direct links to the symbols and abbreviations as they
appear in the modules |
| | Dictionary; giving the German translation of not-so-common English words; again
with direct links to the words as they appear in the modules. All words found in the dictionary are marked
italic, black, and bold. The German translation appears directly on the page if
you move the cursor on it |
| All lists are automatically
generated, so errors will occur. |
| | Note:
Italics and red emphasizes something directly, without any cross reference to some
list. |
| | All numbers, chemical symbols
etc. are written with bold character. There is no particular reason for this except that it looks better to
me. |
| | Variables in formulas
etc. are written in italics as it should be - except when it gets confusing. Is v a v as in
velocity in italics, or the greek n? You get the point. |

| The lecture course "Defects in Crystals" attempts to teach all
important structural aspects (as opposed to electronic aspects) of defects in crystals. It covers all types of defects
(from simple vacancies to phase boundaries; including more complicated point defects, dislocations, stacking faults, grain boundaries), their role for properties of materials,
and the analytical tools for detecting defects and measuring their properties |
| | If you are not too sure about the role of defects in
materials science, turn to the preface. |
| | If you want to get an idea of what you should know
and what will be offered, turn to chapter 2 |
| A few more general remarks |
| | The course is far to short to really cover the topic appropriately, but still overlaps somewhat with other
courses. The reasons for this is that defects play a role almost everywhere in materials science so many courses make
references to defects. |
| | The course has a special format
for the exercise part similar to "Electronic Materials", but a bit less formalized.
Conventional exercises are partially abandoned in favor of "professional" presentations including a paper to
topics that are within the scope of the course, but will not be covered in regular class. A list of topics is given in
chapter 1.2.1 |
| The intention
with this particular format of exercises is: |
| | Learn how to
research an unfamiliar subject by yourself. |
| | Learn how to
work in a team. |
| | Learn how to make a scientific presentation
in a limited time (Some hints can be found in the link) |
| | Learn how to write a coherent paper on a well defined subject. |
| | Learn about a new (and hopefully exciting) topic concerning
"defects". |
| Accordingly, the contents and the style
of the presentation will also be discussed to some extent. The emphasize, however, somewhat deviating from
"Electronic Materials", is on content. For details use the link. |
|
|
| The graduate course "Defects in Crystals" interacts with and draws on
several other courses in the materials science curriculum. A certain amount of overlap is unavoidable. Other courses
of interest are |
|
|
|
Introduction to Materials Science I + II ("MaWi I + II";
Prof. Föll) |
| | Required for all "Dipl.-Ing." students;
3rd and 4th semester |
| | Undergraduate course, where the essentials
of crystals, defects in crystals, band structures, semiconductors, and properties of semiconductors up to
semi-quantitave I-V-characteristics of p-n-junctions are taught. |
| | For details of contents refer to the Hyperscripts (in german)
MaWi I
MaWi II |
| Physical Metallurgy I
("Metals I", Prof. Faupel) |
| | Includes properties
of dislocations and hardening mechanisms |
| Sensors I |
| | Will, among other topics, treat point defects
equilibria and reactions in the context of sensor applications |
| Materials
Analytics I + II ("Analytics I + II", Prof. Jäger) |
| | Covers in detail some (but not all) of the experimental techniques, e.g. Electron Microscopy |
| Solid State Physics I + II ("Solid State I + II" Prof.
Faupel) |
| | Covers the essentials of solid state physics, but
does not cover structural aspects of defects. |
| Semiconductors (Prof. Föll) |
|
| Covers "everything" about semiconductors except Si technology (but other
uses of Si, some semiconductor physics, and especially optoelectronics).
Optpelectronics needs heterojunctions and heterojunctions are plagued by defects. |
