Supporting data for: Optical properties of electrochemically gated La1-xSrxCoO3-δ as a topotactic phase-change material

The data included here contain the information necessary to recreate the
figures in a manuscript titled "Optical Properties of
Electrochemically Gated La1-xSrxCoO3-δ as a Topotactic Phase-Change
Material". The data files include scanning transmission electron
microscopy (STEM) images of electrochemically gated La1-xSrxCoO3-δ (LSCO)
films, finite-difference time-domain (FDTD)-simulated electric field and
reflectance data for LSCO-based metasurfaces, transfer-matrix model
reflectance data for LSCO films on gold substrates, complex refractive
index data for LSCO films before and after electrochemical gating,
electronic resistivity data for LSCO films before and after
electrochemical gating, source-drain current measurements of LSCO films
during electrochemical gating, and X-ray diffraction data for LSCO films
before and after electrochemical gating.
