Which mechanism causes reduced efficiency when metallic ink is imperfectly sintered?

💡 Explanation

Increased phonon scattering causes lower thermal and electrical conductivity because grain boundaries disrupt the crystal lattice, rather than increased resonance. Therefore, heat and charge transport is impeded rather than enhanced through the intended matrix.
