Discovery of -free high-temperature Ti-Ta-X shape memory alloys from first principles calculations
Alberto Ferrari, Alexander Paulsen, Dennis Langenkämper +6
The rapid degradation of the functional properties of many Ti-based alloys is due to the precipitation of the phase. In the conventional high-temperature shape memory alloy Ti-…
On the segregation of Re at dislocations in the γ' phase of Ni-based single crystal superalloys
Xiaoxiang Wu, Surendra Kumar Makineni, Paraskevas Kontis +4
We report evidence of Re and Mo segregation (up to 2.6 at.% and 1 at.%) along with Cr and Co to the dislocations inside of γ' precipitates in a second generation Ni-based single cr…
Unusual composition dependence of transformation temperatures in Ti-Ta-X shape memory alloys
Alberto Ferrari, Alexander Paulsen, Jan Frenzel +3
Ti-Ta-X (X = Al, Sn, Zr) compounds are emerging candidates as high-temperature shape memory alloys (HTSMAs). The stability of the one-way shape memory effect (1WE), the exploitable…
Infrared transmission spectroscopy of charge carriers in self-assembled InAs quantum dots under surface electric fields
Shovon Pal, Sascha R. Valentin, Nadezhda Kukharchyk +6
We present a study on the intersublevel spacings of electrons and holes in a single layer of InAs self-assembled quantum dots (SAQDs) using Fourier transform infrared (FTIR) transm…
Interaction effects and transport properties of Pt capped Co nanoparticles
A. Ludwig, L. Agudo, G. Eggeler +2
We studied the magnetic and transport properties of Co nanoparticles (NPs) being capped with varying amounts of Pt. Beside field and temperature dependent magnetization measurement…
Tuning the magnetic properties of Co nanoparticles by Pt capping
A. Ebbing, O. Hellwig, L. Agudo +2
We show that by capping Co nanoparticles with small amounts of Pt strong changes of the magnetic properties can be induced. The Co nanoparticles have a mean diameter of 2.7 nm. Fro…
Structural and magnetic characterization of self-assembled iron oxide nanoparticle arrays
M. J. Benitez, D. Mishra, P. Szary +7
We report about a combined structural and magnetometric characterization of self-assembled magnetic nanoparticle arrays. Monodisperse iron oxide nanoparticles with a diameter of 20…
