Thin films are a prerequisite for application of the emergent exotic ground states in iridates that
result from the interplay of strong spin-orbit coupling and electronic correlations. We report on
pulsed laser deposition of Li2IrO3 films on ZrO2:Y (001) single crystalline substrates. X-ray diffraction
confirms preferential (001) and (10-1) out-of-plane crystalline orientations with well
defined in-plane orientation. Resistivity between 35 and 300K is dominated by a three-dimensional
variable range hopping mechanism. The dielectric function is determined by means of spectroscopic
ellipsometry and, complemented by Fourier transform infrared transmission spectroscopy,
reveals a small optical gap of ≈300 meV, a splitting of the 5d-t2g manifold, and several in-gap excitations
attributed to phonons and possibly magnons.
