Abstract

This paper describes a method to achieve rapid pressureless low-temperature sintering of Ag nanoparticles for bonding. Organic shells adsorbing on the surface of Ag nanoparticles to stabilize them were thinned to create a sparse protecting layer. The numerous coherent twin boundaries formed in sintered Ag nanoparticles with a grain size of 21 nm induce ultrahigh thermal conductivity (229 W m−1 K−1), which overcomes the intrinsic defect that metals with nanosized grains generally exhibit a significantly reduced thermal conductivity because of the grain boundary scattering effect.
