摘要:
An enhancement in the electrical performance of low temperature screen printed silver nanoparticles (nAg) has been measured at frequencies up to 220 GHz. We show 1.6 that for frequencies above 80 GHz the electrical losses in coplanar waveguide structures fabricated using nAg at 350 degrees C 5 are lower than those found in conventional thick film Ag conductors consisting of micrometer-sized grains and fabricated at 850 degrees C. The improved electrical performance is attributed to the better packing of the silver nanoparticles resulting in lower surface roughness by a factor of 3. We discuss how the use of silver nanoparticles offers new routes to high frequency applications on temperature sensitive conformal substrates and in sub-THz metamaterials.
