To cast light on how the alloy composition affects $\\kappa_\\ell$, we study this system using the phonon Boltzmann-transport equation within the relaxation time approximation in conjunction with density functional theory.The effect of alloying through mass-disorder scattering is explored using the virtual crystal approximation to sc","authors_text":"Ankita Katre, Clas Persson, Georg K.
