text: 'Ferroelectric domain wall (DW) conductivity (DWC) can be attributed to two
separate mechanisms: (a) the injection/ejection of charge carriers across the
Schottky barrier formed at the (metal-)electrode-DW junction and (b) the transport
of those charge carriers along the DW. Current-voltage (I-U) characteristics,
recorded at variable temperatures from LiNbO3 (LNO) DWs, are clearly able to differentiate
between these two contributions. Practically, they allow us to directly quantify
the physical parameters relevant to the two mechanisms (a) and (b) mentioned above.
These are, for example, the resistance of the DW, the saturation current, the
ideality factor, and the Schottky barrier height of the electrode-DW junction.
Furthermore, the activation energies needed to initiate the thermally activated
electronic transport along the DWs can be extracted. In addition, we show that
electronic transport along LNO DWs can be elegantly viewed and interpreted in
an adapted semiconductor picture based on a double-diode, double-resistor equivalent-circuit
model, the R2D2 model. Finally, our R2D2 model was checked for its universality
by successfully fitting the I-U curves of not only z-cut LNO bulk DWs, but equally
of z-cut thin-film LNO DWs, and of x-cut thin-film DWs as reported in literature.'
