Exposing the hidden influence of selection rules on phonon–phonon scattering by pressure and temperature tuning

In most compounds, a roughly linear rise in thermal conductivity (k) with pressure (P) is observed. Here, the authors predict boron phosphide exhibits what may be the steepest rise in k with P of any compound followed by a peak and drop in k due to the action of phonon-scattering selection rules.
