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. |
