Tomographic reconstruction of quasistatic surface polariton fields
Raphael Hauer, Georg Haberfehlner, Gerald Kothleitner +2
We theoretically investigate the tomographic reconstruction of the three-dimensional photonic environment of nanoparticles. As input for our reconstruction we use electron energy l…
Analyzing Nanogranularity of Focused Electron-Beam-Induced Deposited (FEBID) Materials by Electron Tomography
Cornelia Trummer, Robert Winkler, Harald Plank +2
Nanogranular material systems are promising for a variety of applications in research and development. Their physical properties are often determined by grain sizes, shapes, mutual…
Benefits of direct electron detection and PCA for EELS investigation of organic photovoltaics materials
Georg Haberfehlner, Sebastian F. Hoefler, Thomas Rath +3
Electron energy-loss spectroscopy (EELS) is a powerful tool for imaging chemical variations at the nanoscale. Here, we investigate a polymer/organic small molecule-blend used as ab…
Three dimensional vectorial imaging of surface phonons
Xiaoyan Li, Georg Haberfehlner, Ulrich Hohenester +3
While phonons and their related properties have been studied comprehensively in bulk materials, a thorough understanding of surface phonons for nanoscale objects remains elusive. I…
Large magnetic gap at the Dirac point in a Mn-induced BiTe heterostructure
E. D. L. Rienks, S. Wimmer, P. S. Mandal +15
Magnetically doped topological insulators enable the quantum anomalous Hall effect (QAHE) which provides quantized edge states for lossless charge transport applications. The edge…
In depth nano spectroscopic analysis on homogeneously switching double barrier memristive devices
Julian Strobel, Mirko Hansen, Sven Dirkmann +10
Memristors based on a double barrier design have been analysed by various nano spectroscopic methods to unveil details about its microstructure and conduction mechanism. The device…
Experimental probing of exchange interactions between localized spins in the dilute magnetic insulator (Ga,Mn)N
A. Bonanni, M. Sawicki, T. Devillers +16
The sign, magnitude, and range of the exchange couplings between pairs of Mn ions is determined for (Ga,Mn)N and (Ga,Mn)N:Si with x < 3%. The samples have been grown by metalorgani…
