Abstract

The realization of plasmo-electronic integrated circuits in a silicon chip will be enabled by two new plasmonic materials that are proposed and modeled in this article. The first is ion-implanted Si (n-type or p-type) at the surface of an intrinsic Si chip. The second is a thin-layer silicide such as Pd₂Si, NiSi, PtSi₂ WSi₂ or CoSi₂ formed at the Si chip surface. For doping concentrations of 10²⁰ cm^-3 and 10²¹ cm^-3, our dispersion calculations show that bound surface plasmon polaritons will propagate with low loss on stripe-shaped plasmonic waveguides over the 10 to 55 µm and 2.8 to 15 µm wavelength ranges, respectively. For Pd₂Si/Si plasmonic waveguides, the wavelength range of 0.5 to 7.5 µm is useful and here the propagation lengths are 1 to 2300 µm. For both doped and silicided guides, the SPP mode field extends much more into the air above the stripe than it does into the conductive stripe material.
