Giant isotropic Nernst effect in an anisotropic Kondo semimetal
Ulrike Stockert, Peije Sun, Niels Oeschler +4
The "failed Kondo insulator" CeNiSn has long been suspected to be a nodal metal, with a node in the hybridization matrix elements. Here we carry out a series of Nernst effect exper…
Ferromagnetic Ordering in CeIr2B2: Transport, magnetization, specific heat and NMR studies
A. Prasad, V. K. Anand, U. B. Paramanik +5
We present a complete characterization of ferromagnetic system CeIr2B2 using powder x-ray diffraction XRD, magnetic susceptibility chi(T), isothermal magnetization M(H), specific h…
Thermoelectric properties of lead chalcogenide core-shell nanostructures
Marcus Scheele, Niels Oeschler, Igor Veremchuk +5
We present the full thermoelectric characterization of nanostructured bulk PbTe and PbTe-PbSe samples fabricated from colloidal core-shell nanoparticles followed by spark plasma si…
Single-ion Kondo Scaling of the Coherent Fermi Liquid Regime in Ce1-xLaxNi2Ge2
Adam P. Pikul, Ulrike Stockert, Alexander Steppke +7
Thermodynamic and transport properties of the La-diluted Kondo lattice CeNi2Ge2 were studied in a wide temperature range. The Ce-rich alloys Ce1-xLaxNi2Ge2 were found to exhibit di…
ZT enhancement in solution-grown Sb(2-x)Bi(x)Te3 nanoplatelets
Marcus Scheele, Niels Oeschler, Igor Veremchuk +6
We report a solution-processed, ligand supported synthesis of 15-20 nm thick Sb(2-x)Bi(x)Te3 nanoplatelets. After complete ligand removal by a facile NH3-based etching procedure, t…
Fermi-surface collapse and dynamical scaling near a quantum critical point
Sven Friedemann, Niels Oeschler, Steffen Wirth +6
Quantum criticality arises when a macroscopic phase of matter undergoes a continuous transformation at zero temperature. While the collective fluctuations at quantum-critical point…
