On the Dispersion of Resistivity and Dielectric Constant of Some Semiconductors at Audiofrequencies
Semiconducting ${\mathrm{Ni}}_{0.4}$${\mathrm{Zn}}_{0.6}$${\mathrm{Fe}}_{2}$${\mathrm{O}}_{4}$, prepared in different ways, has been investigated. It appeared that the ac resistivity and the apparent dielectric constant of the material show a dispersion which can be explained satisfactorily with the help of a simple m…
Über Kumulene IV; Oktaheptaene
Abstract Triacetylen liefert mit Benzophenon und mit Fluorenon Oktatriin‐diole, deren Reduktion mit Phosphordijodid (P 2 J 4 ) + Triäthylamin zu Oktaheptaenen führt. Man erhält Lösungen eines violetten und eines blauen Kumulens, deren Absorptionsbanden beschrieben werden. Durch „Einbettung”︁ in kristallisiertes Benzop…

The growth of crystals and the equilibrium structure of their surfaces
Abstract Parts I and II deal with the theory of crystal growth, parts III and IV with the form (on the atomic scale) of a crystal surface in equilibrium with the vapour. In part I we calculate the rate of advance of monomolecular steps (i.e. the edges of incomplete monomolecular layers of the crystal) as a function of…
