Advanced Photonics Research, Volume 2, Issue 7, July 2021., 2021 The insertion of a thin MgO interlayer for TiN on Si (001) leads to cube‐on‐cube epitaxy of TiN films on Si with significantly improved plasmonic quality. The TiN/MgO/Si structure enables access to the hybrid‐plasmonic‐photonic waveguide platform with sufficiently low losses, and thus long propagation lengths from microns to tens of micrometers, for ...
