Atomic scale spectral control of thermal transport in phononic crystal superlattices
D. Meyer, V. Roddatis, J. P. Bange +12
We present experimental and theoretical investigations of phonon thermal transport in (LaMnO)/(SrMnO) superlattices (LMO/SMO SLs) with the thickness of individual l…
Bandgap measurement of high refractive index materials by off-axis EELS
Maryam Vatanparast, Ricardo Egoavil, Turid W. Reenaas +3
In the present work, Cs aberration corrected and monochromated scanning transmission electron microscopy electron energy loss spectroscopy STEM-EELS has been used to explore experi…
Extreme mobility enhancement of two-dimensional electron gases at oxide interfaces via charge transfer induced modulation doping
Y. Z. Chen, F. Trier, T. Wijnands +22
The discovery of two-dimensional electron gases (2DEGs) at the interface between two insulating complex oxides, such as LaAlO3 (LAO) or gamma-Al2O3 (GAO) epitaxially grown on SrTiO…
Atomic resolution mapping of phonon excitations in STEM-EELS experiments
R. Egoavil, N. Gauquelin, G. T. Martinez +3
Atomically resolved electron energy-loss spectroscopy experiments are commonplace in modern aberrationcorrected transmission electron microscopes. Energy resolution has also been i…
Mapping electronic reconstruction at the metal/insulator interfaces in \ce{LaVO_3/SrVO_3} heterostructures
Haiyan Tan, Ricardo Egoavil, Armand Béché +8
A \ce{(LaVO_3)_6/(SrVO_3)_3} superlattice is studied with a combination of sub-Å resolved scanning transmission electron microscopy and monochromated electron energy-loss spectrosc…
Determining the Curie temperature of La0.67Sr0.33MnO3 thin films
Hans Boschker, Jo Verbeeck, Ricardo Egoavil +7
When comparing a set of La0.67Sr0.33MnO3 (LSMO) samples, the Curie temperature (TC) of the samples is an important figure of merit for the sample quality. Therefore, a reliable met…
Preventing the reconstruction of the polar discontinuity at oxide heterointerfaces
Hans Boschker, Jo Verbeeck, Ricardo Egoavil +7
Perovskite oxide heteroepitaxy receives much attention because of the possibility to com- bine the diverse functionalities of perovskite oxide building blocks. A general boundary c…
