In the last decade, Titanium Nitride has emerged as an alternative plasmonic material to noble metals, thanks to its refractory properties and a carrier-lattice thermalization time much faster ( 100 fs), with respect to e.g. gold (~ 1 ps). In this work, we provide a numerical model to unfold TiN ultrafast nonlinear optical response, on a broad spectral range. The calculations are validated on a 200 nm-thick TiN film on glass

Abstract
In the last decade, Titanium Nitride has emerged as an alternative plasmonic material to noble metals, thanks to its refractory properties and a carrier-lattice thermalization time much faster ( 100 fs), with respect to e.g. gold (~ 1 ps). In this work, we provide a numerical model to unfold TiN ultrafast nonlinear optical response, on a broad spectral range. The calculations are validated on a 200 nm-thick TiN film on glassFile in questo prodotto:
