Untersuchungen zum Lumineszenzverhalten des Aluminiumnitrids und der Aufbau einer Kurzzeit-Lumineszenz-Spektroskopie-Apparatur
(2017-07-07)This thesis consists of three different parts. In the first part it gives the reader an overview of the published results describing near band-edge as well as defect related luminescence in aluminium nitride, also presenting ... -
Critical thicknesses in Nb-H thin films: coherent and incoherent phase transitions, change of precipitation and growth modes and ultrahigh mechanical stress
(2016-08-03)For nanoscale systems such as Me-H thin films, changes of physical properties have been suggested to appear below certain critical sizes. The probable existence of these critical sizes and the related changes of thermodynamical ... -
Gestaltung der elektronischen Korrelationen in Perowskit-Heterostrukturen auf atomarer Skala
(2016-01-19)For the deposition of high quality heterostructures consisting of transition metal perovskites a new system for metalorganic aerosol deposition with growth control by in-situ ellipsometry was developed. By numerical ... -
Zusammenspiel von Ladungs-, Gitter- und magnetischen Ordnungen in hochdotierten LCMO Schichten
(2015-07-27)This work is focused on the preparation and characterization of overdoped La_1-xCa_xMnO_3 films on MgO and as freestanding films. The charge ordering transition is being investigated via means of resistance, magnetization, ... -
Kationen-Ordnung in ferri/ferromagnetischen perowskitischen Dünnfilmen
(2015-07-27)A major obstacle to the applicability of oxide perovskites in electrical or spintronic applications is the size of the specific temperatures at which the physical phenomena such as ferromagnetism or high-temperature ... -
Dünne Palladium-Wasserstoff-Schichten als Modellsystem: Thermodynamik struktureller Phasenübergänge unter elastischen und mikrostrukturellen Zwangsbedingungen
(2015-07-07)Using the formation of a hydride phase in palladium-hydrogen thin films with 5 nm to 2000 nm thickness as a model, this work investigates the impact of film thickness as well as microstructural and elastic constraints on ...
