Comparative study of LaNiO/LaAlO heterostructures grown by pulsed laser deposition and oxide molecular beam epitaxy
F. Wrobel, A. F. Mark, G. Christiani +6
Variations in growth conditions associated with different deposition techniques can greatly affect the phase stability and defect structure of complex oxide heterostructures. We sy…
Atomic-resolution TEM Studies of Pillar-Matrix Structures in Epitaxially Grown Ultrathin ZrO2-La2/3Sr1/3MnO3 Films
Dan Zhou, Wilfried Sigle, Eiji Okunishi +4
We studied ZrO2-La2/3Sr1/3MnO3 pillar matrix thin films which were found to show anomalous magnetic and electron transport properties controlled by the amount of ZrO2. With the app…
Rapid appearance of domains upon phase change in KNbO3 - a TEM in-situ heating study
A. F. Mark, W. Sigle
TEM specimens from potassium niobate single crystals were observed while being heated in a TEM. DWs and dislocations were observed; the DWs were mobile. In certain cases the DWs be…
Breaking the Mode Degeneracy of Surface-Plasmon Resonances in a Triangular System
Nahid Talebi, Wilfried Sigle, Ralf Vogelgesang +6
In this paper, we present a systematic investigation of symmetry-breaking in the plasmonic modes of triangular gold nanoprisms. Their geometrical C3 symmetry is one of the simplest…
