This is a
schematic drawing of various crystal lattice defects;
illustrating parts of what this lecture course is
about. |
|
|
 |
It is a remarkable picture because it
keeps popping up - sometimes slightly modified - in books and articles about
defects in crystals. |
|
 |
Well - this is the original. I drew it (manually, with ink and
stencils) in 1976 as part of my Ph.D. work. |
|
|
Since then, this little beauty has started to
migrate around, and the original source
is so obscure that one might consider it lost. |
|
Do I mind? Not at all! I always get a
kick out of running across it every now and then. |
|
|
Having made this statement I sincerely hope that
all my colleagues, whose work I might have used unknowingly in this
Hyperscript, share my feeling. If not, please get in touch, and I will correct
whatever errors and copyright infringements I might have made. |

Now use the link
to an alternative page that shows a real
defect
and gives some reasons why defects are
important. |
|
|
The "print
friendly" and ".pdf" options only work for the
"backbone" part of the Hyperscript (consult the "Matrix of Modules" for the meaning of
"backbone"). |
|
If you click on "Project" in the menu (or here), you will
find some more information about the structure of this Hyperscript and the philosophy behind it. |
|
|
For example, if you like to read
prefaces, you will find it there. |
|
|
Many other
metafiles are also accessible from
there. |
|
|
This particular Hyperscript is
relatively complete. A few modules are
still missing, but all major modules exist. |
|
There are more Hyperscripts
available If you are really curious about the
Hyperscripts of "AMAT",
you will find some information including a guided tour in the link. |
|
The remaining menu buttons (e.g. Indexlist etc.) provide
automatically generated cross-linked lists which might be useful if you are
looking for specific items. |
|
This Hyperscript was not optimized for easy downloading, but contains
good (large-size) illustrations. If you would like to have it, send an e-mail
for a free CD. |
|
|
The Pdf version only contains the
backbone, and pictures are downsized. The Zip version has it all, but it
is 50 MB! |
|
This Hyperscript is essentially a
collection of (embellished) lecture notes. There are certainly still typos and
real mistakes - use at your own risk. |
|
However, Prof. John R. Abelson from the
University of Illinois at Urbana-Champaign was kind enough to read through most
if the Hyperscript and helped me to correct many mistakes. For this I am
indebted to him. |
