In Munich it locked its doctor work 1908 , 1910 habilitierte itself it.In the year after he became a professor for theoretical physics in Zurich, where he remained two years. Appointment followed after Utrecht, Goettingen, 1920 again to Zurich, 1927 to Leipzig and 1934 to the University of Berlin. Since 1935 Debye was a director at the institute for emperor Williamfor physics in Berlin Dahlem. After differences with the National Socialist regime over its Netherlands nationality he taught since 1939 to the Cornell University in Ithaca, New York.

It was member of the Saxonian Academy of Sciences in Leipzig.

Debye received to 1936 the Nobelpreis forChemistry “for its contributions to our knowledge of the molecular structures by its research of dipole moments, of the diffraction of X-ray and at electrons in gases “. 1950 were lent to it the Max-Planck medal.

Peter Debye died to 2. November 1966 in Ithaca/New York at the consequencesa heart illness.

scientific achievements

Debye above all contributions within the range quantum physics ( Debye model to understand the specific thermal capacity of subject close 0 Kelvin, orbital model) carried, for the electrochemistry out (ion activities, Debye radius), the x-ray structure analysis (Debye Scherrer procedure), for the chemistry of electrolytic solutions (Debye Hückel theory) and the Mikrowellenspektroskopie of liquids (Debye function)In its late researcher years concern itself it with the understanding of polymer molecules. Debye worked in particular in the molecular research. it received the Nobelpreis for chemistry to 1936 “for its contributions to our knowledge of the molecular structures by its research over dipole moments (Debye equation), over diffraction thatX-ray and electrons in gases. “

It made crucial contributions for the methodology of Roentgen crystallography (Debye Scherrer procedure) and for the theory of the polarizing effect of electrical fields on molecules (Debye Hückel theory).

After Peter Debye is designated cgs - the unit of the electrical dipole moment Debye.
