The specified domain patterns were written by AFM-tip voltages in LiNbO3 films composing LNOI (LiNbO3-on-insulator). The domain wall conductivity (DWC) was estimated in the written patterns. This estimate was based on the effects of load resistors RL inserted between DWs and the ground, on the features of occurring domains. In this case, the domain formation is controlled by the ratio between RL and the DWs’ resistance RDW. Starting from the comparison of patterns appearing at different RL, the value of RDW in a specified pattern was estimated. The corresponding DWC is of σDW ≈ 10−3 (Ohm cm)−1 which exceeds the tabular bulk conductivity of LiNbO3 by no less than twelve orders of magnitude. A small DW inclination angle of (10−4)0 responsible for this DWC is not caused by any external action and characterizes the domain frontal growth under an AFM-tip voltage.

This chapter concerns DW electrical conduction. It first addresses the phenomenology of charged domain walls in the context of a Landau-Ginzburg-Devonshire (LGD) model for the ferroelectric semiconductor with analysis of the DW conductivity associated with accumulation of charge carriers near domain walls. It is revealed that there exists an interplay between the wall type — head-to-head or tail-to-tail — and conduction type of the semiconductor ferroelectric with a strong dependence of the domain wall conductivity on the wall orientation. The chapter then reviews observations of high-frequency — in the gigahertz frequency range — ac conductivity along the nominally uncharged 180-degree domain walls in a uniaxial Pb(Zr0.2Ti0.8)O3 epitaxial film. Measurements of the conduction at high frequencies are insensitive to presence of a Schottky barrier and the electrode-ferroelectric interface.
