Abstract

Neue Welt entdeckt: Die Titelverbindungen mit stöchiometrischen Zusammensetzungen, die mit der Formulierung für klassische Zintl-Phasen übereinstimmen, liegen in einer für derartige Strukturen neuen Region des Phasenraums. Die Ergebnisse von DFT-Rechnungen und die diamagnetischen Suszeptibilitäten deuten auf kleine Halbleiterlücken hin.
