    Notes: Abstract This paper considers the Hg1−x Zn x Te alloy system as a potential material for the fabrication of infrared photodiodes. The influence of different junction current components (diffusion, tunneling and depletion layer currents) on the R 0 A product of n+-pHg1−x Zn x Te photodiodes is analysed. The upper theoretical limits of the R 0 A product and detectivity are determined. Results of calculations are compared with experimental data reported by other authors and those measured in our laboratory. Preliminary results on related technology and the properties of Hg1−x Zn x Te prepared by the ion-etching technique are presented.

    Description / Table of Contents: Zusammenfassung Anorganisches Quecksilber, Ratten in einer einzelnen Dose von 0,5 mg Hg/kg verabreicht, wurde in den Nieren vorwiegend in der löslichen (54%) und in der Kern-Fraktion (30%) angereichert, und in beiden Fraktionen wurde eine zeitabhängige Abnahme festgestellt. In der mitochondrialen und mikrosomalen Fraktion, in denen zuerst ca. 11 und 6% Quecksilber gefunden wurde, konnte über die erste Woche eine zunehmende Tendenz festgestellt werden. In der löslichen Fraktion waren die metallothionein-ähnlichen Eiweißstoffe von niedrigem Molekulargewicht vorwiegend für die Bindung von Quecksilber verantwortlich. In anderen Zell-Fraktionen war Quecksilber meistens an Eiweiß-stoffe von hohem Molekulargewicht gebunden.
    Notes: Abstract Inorganic mercury, administered to rats in a single dose of 0.5 mg Hg/kg is accumulated in the kidneys mainly in the soluble (54%) and nuclear (30%) fractions, showing decreasing tendency with time. Mitochondrial and microsomal fractions, initially accumulating approx. 11 and 6% of total Hg, show a tendency to increase the absolute level of Hg for the first week after administration. In the soluble fraction low-molecular weight, metallothioneinlike proteins are mainly responsible for the accumulation of mercury, in other fractions proteins of higher molecular weight prevail.
