Approaching the Limit of Intrinsic Crystalline Thermal Insulation
Ruihuan Cheng, Zhiqiang Cui, Mani Jayaraman +9
Crystalline materials with ultralow thermal conductivity () are potential thermal barrier coatings or thermoelectrics, yet the discovery of ultralow- materials remains inef…
Thermal conductivity of CdCrSe ferromagnet at low temperatures: role of grain boundaries and porosity
JiÅà Hejtmánek, Kyo-Hoon Ahn, ZdenÄk Jirák +5
It is unambiguously demonstrated that the low temperature magnon specific heat in a ferromagnet varies as T and the magnon thermal conductivity, due to T - dependen…
Phonon properties and unconventional heat transfer in quasi-2D crystal
Jan Zich, AntonÃn Sojka, Petr Levinský +10
Bi2O2Se belongs to a group of quasi-2D semiconductors that can replace silicon in future high-speed/low-power electronics. However, the correlation between crystal/band structure a…
Accelerated Discovery of Crystalline Materials with Record Ultralow Lattice Thermal Conductivity via a Universal Descriptor
Xingchen Shen, Jiongzhi Zheng, Michael Marek Koza +9
Ultralow glass-like lattice thermal conductivity in crystalline materials is crucial for enhancing energy conversion efficiency in thermoelectrics and thermal insulators. We introd…
Two-component anomalous Hall and Nernst effects in anisotropic FeGeN thin films
R. K. Paul, J. VÃt, P. Levinský +18
A series of thin films FeGeN (x=0-1) was fabricated onto MgO substrates by magnetron sputtering with the aim of studying the possible enhancement of the anomalous Nerns…
