Advancing Atom Probe Tomography of SrTiO: Measurement Methodology and Impurity Detection Limits
J. E. Rybak, J. Arlt, B. Gault +1
Strontium titanate (STO) possesses promising properties for applications in thermoelectricity, catalysis, fuel cells, and more, but its performance is highly dependent on stoichiom…
Nanoscale friction controlled by top layer thickness in [LaMnO]/[SrMnO] superlattices
Niklas A. Weber, Miru Lee, Florian Schönewald +4
We conducted lateral force microscopy measurements on seven [LaMnO]/[SrMnO] superlattices with varied layer thicknesses. We observe that the friction forces…
Friction on layered media: How deep do phonons reach?
Miru Lee, Niklas Weber, Cynthia A. Volkert +1
We theoretically study the frictional damping of a small probe object on a coated planar surface, analyzing the resulting phonon modes via a theory of viscoelasticity. Three differ…
Noncontact friction: Role of phonon damping and its nonuniversality
Miru Lee, Richard L. C. Vink, Cynthia A. Volkert +1
While obtaining theoretical predictions for dissipation during sliding motion is a difficult task, one regime that allows for analytical results is the so-called noncontact regime,…
Friction on incommensurate substrates: Role of anharmonicity and defects
S. Amiri, C. A. Volkert, R. L. C. Vink
We present Molecular Dynamics simulations of one- and two-dimensional bead-spring models sliding on incommensurate substrates. We investigate how sliding friction is affected by in…
Polaronic Contributions to Friction in a Manganite Thin Film
Niklas A. Weber, Hendrik Schmidt, Tim Sievert +6
Despite the huge importance of friction in regulating movement in all natural and technological processes, the mechanisms underlying dissipation at a sliding contact are still a ma…
