Description

Als Photoscbicfaten für Vidikons wurde bisher vornehmlich Selen in roter amorpher Modifikation benutzt. Der Nachteil dieser .Schichten liegt in der außerordentlich starken Temperaturabhängigkeit. Über so0 C werden diesel Schichten bereits, instabil und lassen sich praktisch nur bei Temperaturen zwischen io und 300 C verwenden.Selenium in red amorphous modification has so far primarily been used as photoscbicfate for vidikons. The disadvantage of these .Schichten is the extremely strong temperature dependence. Above this 0 C, these layers already become unstable and can practically only be used at temperatures between 10 and 30 ° C.

Sehr ähnlich verhalten sich Schichten aus Antimon-Trisulfid, wenn die Werte hier auch schon um Weniges besser liegen.Layers made of antimony trisulfide behave in a very similar manner, even if the values are a little better here.

Nach der vorliegenden Erfindung werden nun statt dieser bekannten Schichten solche nach der im Hauptpatent geschützten Art verwendet, die aus Cadmium-Sulfid . bestehen. Bei der Herstellung einer solchen Schicht wird der zu behandelnde Halbleiter in ein Pulver eingebettet, das aus dem gleichen oder einem verwandten Grundmaterial besteht wie der zu behandelnde Halbleiter und dessen Zusammensetzung der für dien zu behandelnden Halbleiter gewünschten entspricht. Das Pulver mit den eingebetteten Halbleitern wird erhitzt, und die für eine Thermodiffusion ausreichende Temperatur wird so lange aufrechterhalten, bis sich die verschiedenen Störstellenkonzentrationen oder Abweichungen vom stöchiometrischen Verhältnis der Grund-Substanzen zwischen Einbettpulver und zu behan-According to the present invention, instead of these known layers, those according to the im Main patent protected kind used made from cadmium sulfide. exist. In the preparation of Such a layer, the semiconductor to be treated is embedded in a powder that consists of the the same or a related basic material as the semiconductor to be treated and its Composition of the desired for the semiconductor to be treated corresponds. The powder with the embedded semiconductors is heated, and the temperature sufficient for thermal diffusion is maintained until the different Impurity concentrations or deviations from the stoichiometric ratio of the basic substances between embedding powder and to be treated

delnden Halbleiter ausgeglichen haben. Das Verfahren und seine Vorteile sind im Einzelnen im Hauptpatent eingehend dargelegt.have compensated for the delnding semiconductor. The procedure and its advantages are detailed in Main patent set out in detail.

Verwendet man nun derartige Schichten als Photoschichten für Vidikons, so treten auf diesem Gebiet ganz besondere Vorteile gegenüber den bisher verwendeten Photoschichten ein.If you now use such layers as photo layers for vidikons, you step on this Area has very special advantages over the previously used photo layers.

Die Cadmium-Sulndschdcht ist praktisch völlig temperaturunabhängig: Bei nicht allzulanger Belastung treten Veränderungen kaum unter 31600 C ein und außerdem liegt, was für die Funktion des Vidikon von ausschlaggebender Bedeutung ist, die Empfindlichkeit dieser neuen Schichten etwa um den Faktor io3 höher als bei den bisher üblichen Photoschichten. Ein weiterer Vorteil liegt in der spektralen' Verteilung. Durch besondere Aktivatoren, z. B. Kupfer, Selen, Nickel und anderes mehr, kann das Maximum der Empfindlichkeit in jeden gewünschten IS'pektraJbereieh gelegt werden.The cadmium Sulndschdcht is almost completely independent of temperature: In not too long load changes occur hardly 3160 0 C and also is what is the function of the vidicon crucial, the sensitivity of these new layers higher by about a factor io 3 than in the previously usual photo layers. Another advantage is the spectral distribution. Through special activators, e.g. B. copper, selenium, nickel and others, the maximum sensitivity can be placed in any desired range.
