Hybrid ab initio method for examining thermal properties in magnetic materials
Matthew Heine, Olle Hellman, David Broido
A hybrid ab initio theoretical approach for examining thermal properties in magnetic systems of unknown entropy is presented. Commonly used theoretical approaches interrogate therm…
How do defects limit the ultrahigh thermal conductivity of BAs? A first principles study
Mauro Fava, Nakib Haider Protik, Chunhua Li +6
The promise enabled by BAs high thermal conductivity in power electronics cannot be assessed without taking into account the reduction incurred when doping the material. Using firs…
Phonon-Phonon Interactions in Strongly Bonded Solids: Selection Rules and Higher-Order Processes
Navaneetha K. Ravichandran, David Broido
We show that the commonly used lowest-order theory of phonon-phonon interactions frequently fails to accurately describe the anharmonic phonon decay rates and thermal conductivity…
Thermodynamic Evidence of Proximity to a Kitaev Spin-Liquid in AgLiIrO
Faranak Bahrami, William Lafargue-Dit-Hauret, Oleg I. Lebedev +5
Kitaev magnets are materials with bond-dependent Ising interactions between localized spins on a honeycomb lattice. Such interactions could lead to a quantum spin-liquid (QSL) grou…
Coupled transport of phonons and carriers in semiconductors: A case study of n-doped GaAs
Nakib H. Protik, David A. Broido
We present a general coupled electron-phonon Boltzmann transport equations (BTEs) scheme designed to capture the mutual drag of the two interacting systems. By combining density fu…
Thermal expansion coefficient and lattice anharmonicity of cubic boron arsenide
Xi Chen, Chunhua Li, Fei Tian +6
Recent measurements of an unusual high thermal conductivity of around 1000 W m-1 K-1 at room temperature in cubic boron arsenide (BAs) confirm predictions from theory and suggest p…
