Which mechanism reduces thermal conductivity in semiconductor alloys?

💡 Explanation

Alloying changes composition, therefore phonon scattering increases, disrupting phonon band structure, decreasing thermal conductivity, rather than electronic effects causing thermal changes. The mechanism is phonon scattering.
