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. |
