Mass sensing for the advanced fabrication of nanomechanical resonators
G. Gruber, C. Urgell, A. Tavernarakis +7
We report on a nanomechanical engineering method to monitor matter growth in real time via e-beam electromechanical coupling. This method relies on the exceptional mass sensing cap…
Interrelation of elasticity and thermal bath in nanotube cantilevers
S. Tepsic, G. Gruber, C. B. Moller +6
We report the first study on the thermal behaviour of the stiffness of individual carbon nanotubes, which is achieved by measuring the resonance frequency of their fundamental mech…
Metallic Diluted Dimerization in VO2 Tweeds
Felip Sandiumenge, Laura Rodriguez, Miguel Pruneda +3
The observation of electronic phase separation textures in vanadium dioxide (VO2), a prototypical electron-correlated oxide, has recently added new perspectives on the long standin…
Artificial double-helix for geometrical control of magnetic chirality
Dédalo Sanz-Hernández, Aurelio Hierro-Rodriguez, Claire Donnelly +9
Chirality plays a major role in nature, from particle physics to DNA, and its control is much sought-after due to the scientific and technological opportunities it unlocks. For mag…
Nanowire magnetic force sensors fabricated by focused electron beam induced deposition
H. Mattiat, N. Rossi, B. Gross +6
We demonstrate the use of individual magnetic nanowires (NWs), grown by focused electron beam induced deposition (FEBID), as scanning magnetic force sensors. Measurements of their…
Tunable resistivity exponents in the metallic phase of epitaxial nickelates
Qikai Guo, Saeedeh Farokhipoor, César Magén +2
We report a detailed analysis of the electrical resistivity exponent of thin films of NdNiO3 as a function of epitaxial strain. Strain-free thin-films show a linear dependence of t…
Observation of hedgehog skyrmions in sub-100 nm soft magnetic nanodots
Eider Berganza, Miriam Jaafar, Maite Goiriena-Goikoetxea +7
Magnetic skyrmions are nanometric spin textures of outstanding potential for spintronic applications due to unique features governed by their non-trivial topology. It is well known…
Magnetic properties of optimized cobalt nanospheres grown by Focused Electron Beam Induced Deposition (FEBID) on cantilever tips
Soraya Sangiao, Cesar Magen, Darius Mofakhami +2
In this work, we present a detailed investigation of the magnetic properties of cobalt nanospheres grown on cantilever tips by Focused Electron Beam Induced Deposition (FEBID). The…
Electron degeneracy and intrinsic magnetic properties of epitaxial Nb:SrTiO thin-films controlled by defects
A. Sarantopoulos, E. Ferreiro-Vila, V. Pardo +3
We report thermoelectric power experiments in e-doped thin films of SrTiO (STO) which demonstrate that the electronic band degeneracy can be lifted through defect management du…
Exciton Footprint of Self-assembled AlGaAs Quantum Dots in Core-Shell Nanowires
Yannik Fontana, Pierre Corfdir, Barbara Van Hattem +7
Quantum-dot-in-nanowire systems constitute building blocks for advanced photonics and sensing applications. The electronic symmetry of the emitters impacts their function capabilit…
Screening of the quantum-confined Stark effect in AlN/GaN nanowire superlattices by Germanium doping
P. Hille, J. Müßener, P. Becker +8
We report on electrostatic screening of polarization-induced internal electric fields in AlN/GaN nanowire heterostructures with Germanium-doped GaN nanodiscs embedded between AlN b…
