Title: Epitaxial thin film growth and properties of unconventional superconductors
Language: English
Abstract:

The discovery of high-temperature superconductors has strongly driven the development of suited thin film fabrication methods of complex oxides. One way is the adaptation of molecular beam epitaxy (MBE) for the growth of oxide materials. Another approach is the use of pulsed laser deposition (PLD) which has the advantage of good stoichiometry transfer from target to the substrate. Both techniques are used within this thesis. Epitaxial thin films of new materials are of course needed for future applications. In addition, the controlled synthesis of thin film matter which can be formed far away from thermal equilibrium allows for the investigation of fundamental physical materials properties.

Die Entdeckung der Hochtemperatursupraleitung hat die Entwicklung geeigneter Duennschichtherstellungsmethoden fuer komplexe Oxide stark beeinflusst. Eine Moeglichkeit stellt die Adaption der Molekularstrahl Epitaxie fuer das Wachstum oxidischer Materialien dar. Daneben existiert fuer das Wachstum oxidischer Materialien die Methode der gepulsten Laserdeposition, die sich durch einen genauen Stoechiometrieuebertrag vom Target zum Substrat auszeichnet. In dieser Dissertation wurden beide Verfahren verwendet. Fuer zukuenftige Anwendungen sind epitaktisch gewachsene Schichten neuer Materialien von hoher Bedeutung. Darueber hinaus erlaubt das kontrollierte Wachstum duenner Schichtmaterialien, welches typischerweise entfernt vom thermodynamischen Equilibrium statt findet, Untersuchungen fundamentaler phyikalischer Materialeigenschaften.German
