Abstract

Titanium nitride (TiN_x) is regarded as a kind of promising plasmonic material for its high performances. We studied the influence of nitrogen partial pressure p_n and deposition temperature T_d on the structural and plasmonic properties of the TiN_x thin films prepared by ion beam assisted deposition (IBAD). The results show that IBAD is an effective method to tailor the plasmonic properties of TiN_x films in visible and near-IR region. The plasmonic properties of the films have significant T_d and p_n dependence. Higher p_n and lower T_d can reduce the plasma frequency and the plasmon resonance. Higher p_n and higher T_d can reduce the optical loss of the samples. The modification of the plasmonic properties is related to the variation of nitrogen content.
