Welcome! This is the personal page of
So far, besides a short CV, there is mainly
an overview of my publications (last update:
04 November 2019). There you find my Ph. D. thesis as well as works on nitride semiconductors,
silicon-related interfaces, silicon solar cells, thermography, the Peltier effect, and other

As a by-product of my teachings, for the students I collected background information on the
status of photovoltaic energy in Germany and worldwide. This collection became a long list
of hyperlinks, which I arranged as a “guided tour” motivated by questions I consider
most relevant: Informationen zur Photovoltaik (in German, work
in progress; last update: 17 October 2018).
Very interesting: Friedrich
Schiller’s famous speech that he started his historical lectures in Jena with.
It is entitled “Was heißt und zu welchem Ende
studiert man Universalgeschichte? (Eine akademische Antrittsrede.)”.

Or, as the media now claim, 2005? Well, the most recent stuff about this subject can

“Schrift & Rede”,
the web site of “Forschungsgruppe Deutsche Sprache e.V. (FDS)”, a registered

Here you can find a largely documentary (and partially commentary) German text that I
originally wrote back in 2004 and which I reworked a little in 2009,
“Zum Hintergrund der
Rechtschreibreform”. In making this web version (via
I recently have just tried to find the originally referenced pages in the web archive.
Additionally I want to bring two archive pages of a former colleague of mine (Dr.
Hans-Christian Weissker) to your attention:
“Warum die Rechtschreibreform gefährlich ist”
(short overview with further links) and
“Die Rechtschreibreform und einige ihrer Argumente”
(complete essay; very goood).
