Query: Homogeneous superconducting phase in TiN film : a complex impedance
  study   The low frequency complex impedance of a high resistivity 92 {\mu}{\Omega} cm
and 100 nm thick TiN superconducting film has been measured via the
transmission of several high sensitivity GHz microresonators, down to Tc/50.
The temperature dependence of the kinetic inductance follows closely BCS local
electrodynamics, with one well defined superconducting gap. This evidences the
recovery of an homogeneous superconducting phase in TiN far from the disorder
and composition driven transitions. Additionally, we observe a linearity
between resonator quality factor and frequency temperature changes, which can
be described by a two fluid model.
