We studied the thermal conduction of thermal interface materials (TIM) using silver nanoparticles (AgNP) and achieved ultra-low thermal resistance. The experimental data show that silver nanoparticles are very good candidates for TIM in power electronics applications in terms of the reduction in thermal resistance. The ultra-low thermal resistance of the AgNP-based TIM originates from the thinness, high thermal conductivity of silver and low temperature sintering properties of AgNP.
