abstract = {SrTiO3 (100) epitaxial films with thicknesses of 3, 1 μm,
and 250 nm were prepared on MgO (100) substrates by
pulsed-laser deposition. The electrical conductivities of
the thin films were systematically investigated as a
function of temperature and ambient oxygen partial pressure.
This was made possible by using a specially designed
measurement setup, allowing the reliable determination of
resistances of up to 25 GΩ in the temperature range of
600°–1000°C under continuously adjustable oxygen partial
pressures ranging from 10−20 to 1 bar. The capabilities of
the measurement setup were tested thoroughly by measuring a
SrTiO3 single crystal. The well-known characteristics, e.g.,
the decline of the conductivity with a slope of –1/4 under
reducing conditions and the opposite +1/4 behavior in
oxidizing atmospheres, are found in the log(σ)–log(pO2)
profiles of the epitaxial films. However, the p-type
conductivity decreases, and the n-type conductivity
increases with decreasing film thickness. This phenomenon is
attributed to the charge carrier redistribution in the
surface space charge layers. Owing to the high
surface-to-volume ratio, the space charge layers play an
important role in thin films.},
