Auf Grund der stetig wachsenden Bedeutung der Nachrichten- und Kommunikationstechnik in der modernen Informationsgesellschaft, sowie der ständigen Forderung nach höheren Datenübertragungsraten, steigt der weltweite Bedarf an qualitativ hochwertigen InP Substratkristallen kontinuierlich an. Nach allgemeiner Einschätzung stellen das vertikale Gradient Freeze (VGF) Verfahren und verwandte Züchtungstechniken die einzige Möglichkeit dar die wachsenden Anforderungen an qualitativ hochwertige Substrate bei einer weiteren Steigerung des Kristalldurchmessers zu erfüllen. Um den Einfluss der Züchtungsbedingungen auf das Auftreten von Defekten (polykristallines Wachstum, Versetzungen, Zwillinge) zu untersuchen und mit den so gewonnenen Erkenntnissen d...
