  bibo_abstract:
  - "The comprehensive description of both the electrical transport along conductive
    domain walls in lithium niobate single crystals and the charge injection at the
    interfacing metal electrodes, emerged to be a complex challenge. Recently, a heuristic
    evaluation allowed to postulate the “\U0001D445⁢2⁢\U0001D437⁢2\r\n” equivalent-circuit
    model (consisting of two parallel resistor-diode pairs) to appropriately match
    the dc current-voltage (I-V) characteristics. Here, we carefully revisit the interfacial
    electrical behavior, i.e., the diode part of the equivalent circuit model, since
    many more processes beyond the diode-related electron hopping transport (HT) assumed
    so far, may concurrently occur, such as thermionic emission (TE), Fowler-Nordheim
    tunneling (FNT), space-charge limited conduction (SCLC), and others. The “\U0001D445⁢2⁢\U0001D437⁢2\r\n”
    model thus needs to be generalized into an “\U0001D445⁢2⁢\U0001D44B⁢2\r\n” circuit
    model (with \U0001D44B\r\n= HT, TE, FNT, SCLC, and others) to fit to the experimental
    data. Moreover, to check for the best I-V curve fitting to the different theories,
    we apply a higher-harmonic DW current-contribution analysis, i.e., an ac I-V inspection,
    that allows us to discriminate between all these possible models with much higher
    precision than from pure dc I-V curve fitting. Both the ac and dc analysis yield
    consistent results, finding that the FNT model accounts best for the domain-wall/electrode
    junctions investigated here.@eng"
