Untersuchung der strukturellen Phasenübergänge und Domänenbildung in den ferroischen Modellsubstanzen RbH 2 PO 4 und RbD 2 PO 4
RDP (RbH2PO4) belongs to the well known family of hydrogen bonded ferroelectrics with the composition A(H,D)2XO4 (A=K,Rb,Cs,Tl and X=P,As). On KDP (KH2PO4), the root member of the family, Busch and Scherrer discovered in 1935 the ferroelectric behaviour. A rich number of works concerning the …

Multiferroische Schichtsysteme: Piezoelektrisch steuerbare Gitterverzerrungen in Lanthanmanganat-Dünnschichten
In der vorliegenden Arbeit werden durch den inversen piezoelektrischen Effekt kontrolliert Dehnungen in Lanthanmanganatschichten eingebracht und ihr Einfluss auf die Eigenschaften der Schichten untersucht. Dazu wird im ersten Teil der Arbeit ein Zweischichtsystem bestehend aus einer Manganatschicht …

Impact of the interface on the paraelectric to ferroelectric phase transition in expitaxial BaSrTiO 3 thin film capacitors
The ever increasing memory densities of the so called Dynamic Random Access Memory (DRAM) lead to a drastic reduction of the area of the incorporated storage capacitors. As a consequence, the film thickness of the used dielectrics has to be decreased in a similar way. When considering …
