Es wurde festgestellt, dass eine Anzahl Metalle, die als Legierungsbestandteil einer lli-P-Legierung zugesetzt werden, einen unvoraussagbaren Einfluss auf deren spezifische Leitfähigkeit ausüben. Ausser dem im Rahmen der Erfindung brauchbaren Bestandteil Zn wurden noch andere Elemente untersucht. Es wurde gefunden, dass Gd und Mn auch den Widerstandswert steigern, aber auf sehr unreproduzierbare Weise, während auch Pe diesen Wert steigert, aber in unwesentlichem Masse. Weiter wurde gefunden, dass Wolfram und Aluminium den Widerstandswert herabsetzen, während Ca und Ba überraschenderweise gar kein Widerstandsmaterial liefern.It has been found that a number of metals classified as Alloy constituent of an III-P alloy are added, a have an unpredictable influence on their specific conductivity. In addition to the component Zn which can be used in the context of the invention, other elements were also investigated. It was found that Gd and Mn also denote Increase the resistance value, but in a very unreproducible way, while Pe also increases this value, but to an insignificant extent. It was also found that tungsten and aluminum reduce the resistance value, while Ca and Ba surprisingly do not have any resistance material at all deliver.
