Enhanced Electrical Conductivity of Silver Nanoparticles for High Frequency Electronic Applications

Abstract

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 that for frequencies above 80 GHz the electrical losses in coplanar waveguide structures fabricated using nAg at 350 o C are lower than those found in conventional thick film Ag conductors consisting of micron-sized grains and fabricated at 850 o C. The improved electrical performance is attributed to the better packing of the silver nanoparticles resulting in lower surface roughness by a factor of three. 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.

“…[1][2][3][4] The interest in nanoparticles arises from their size, shape and surface morphology that ultimately determines their chemical, physical, optical and electronic properties. 5 Conventional chemical and physical methods used to prepare nanoparticles often use toxic materials and processes that are not environmentally friendly and present many hazards.…”

A Review On The Diverse Application Of Silver Nanoparticle

“…The effect is typically 100 times stronger than for a bulk metal surface, and is readily discernible to the unaided eye. The ER effect makes it possible to directly monitor the changes in the electrostatic charge stored on small metal particles using absorption spectroscopy [21].…”

“…Уникальные физико-химические, оптические и био-логические свойства наночастиц серебра (НЧ Ag) обусловливают обширные области их применения: в спектроскопии для детектирования различных анали-тов [1], в химическом катализе [2], электронике [3]. В связи с антибактериальными и противовирусными свойствами большой интерес НЧ Ag представляют и для медицины [4,5].…”
