Erich Mollwo

from Wikipedia, the free encyclopedia

Erich Mollwo (born June 23, 1909 in Göttingen ; † December 11, 1993 in Erlangen ) was a German solid-state physicist who was a professor at the University of Erlangen .

Life

Mollwo was the grandson of Woldemar Voigt on his mother's side and his father Ludwig Mollwo was a professor of history at the TH Hannover. From 1928 he studied mainly physics at the Ludwig Maximilians University in Munich and the University of Göttingen , where he received his doctorate in 1933 under Robert Wichard Pohl on alkali halide crystals ( on the knowledge of light absorption in alkali halide crystals , 1933) and was Pohl's assistant. In 1937, after completing his habilitation, he became a private lecturer and in 1944 an extraordinary professor. In 1948 he became professor for applied physics at the University of Erlangen on a newly created chair and director of the newly created institute for applied physics. He turned down an offer to become head of AEG's research institute . In 1976 he retired.

In Göttingen he initially researched one of Pohl's main areas of research, alkali halide crystals, and in 1932 discovered the Mollwo relationship in their spectra (dependence of the frequency of the maximum absorption of color centers on the number of lattices), which led to one of the first models of impurities in solid state physics. In addition, he was already working in Göttingen from 1944 onwards with semiconductors and especially with zinc oxide, a II-VI semiconductor, which he later researched, preferably in all directions, in solid-state physics at a time when other semiconductors were much more popular. Like his teacher Pohl, he devoted himself to demonstration experiments for the physics lecture in Erlangen and was known there for these experimental physics lectures.

He was a member of the Bavarian Academy of Sciences and the New York Academy of Sciences.
