Abstract

Titanium nitride (TiN) with excellent optical and thermal properties has recently attracted attention in the fields of plasmonics and photothermal applications. We report the dielectric as well as the transient optical responses of ultrathin TiN and Ti_1-xAl_xN (0fxf0.67) films grown by molecular-beam-epitaxy method. With increasing Al compositions, drastic increase of VIS-NIR absorption and the redshift of the epsilon-near-zero wavelength is observed for Ti_1-xAl_xN. Strong sub-picosecond electron-phonon coupling and nanosecond-long heatpreservation is observed for Ti_1-xAl_xN in the whole visible spectral range.
