- W2044131504 abstract "Two classes of experimental results are presented of reducing the copper contamination in germanium on heat treatments above 700 °C. The first class of the results presented is concerned with the comparison of various gettering techniques developed so far. The gallium coating is found to be the best in view of the gettering ability and the convenience of application. It is essentially important in this technique to pre-heat Ga-coated samples at 700 °C for 1 h prior to the main heat treatments at any higher temperatures. The second class are the results of the degree of copper contamination in various furnaces. Conventional resistance-heated furnaces with nichrome-wire heaters or Sic heating elements are not suitable for high-purity heat treatments, since the heaters may possibly be a principal source of the contamination. The infrared furnace shows a low density of contaminating copper, ≈ 1013cm−3, on heat treatments at 700 °C.Zur Frage, wie man die Verunreinigung von Germanium mit Kupfer durch Gluhungen bei Tem-peraturen oberhalb von 700 °C reduziert, werden zwei experimentelle Ergebnisse mitgeteilt. Das erste Ergebnis betrifft den Vergleioh verschiedener bisher entwickelter Gettermethoden. Es wird gefunden, das die Bedeckung mit Gallium bezuglich Getterstarke und Handhabbarkeit das beste Verfahren ist. Es ist dabei sehr wichtig, die mit Gallium bedeckten Proben vor der Hauptgliihung 1 h bei 700 °C vorzutempern. Das zweite Ergebnis betrifft den Verunreinigungsgrad mit Kupfer bei Benutzung verschiedener Ofen. Konventionelle Widerstandsofen mit NiCr-Drahten oder Sic-Heizelementen sind fur saubere Gluhbehandlungen nicht geeignet, da die Ofen moglicherweise die Hauptquellen der Verunreinigung sind. Der Infrarotofen ergibt nach Gluhbehandlungen bei 700 °C eine geringere Verunreinigung der Proben mit Kupfer (≈ 1013 cm−3)." @default.
