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…
