  bibo_abstract:
  - In the last decade, conductive domain walls (CDWs) in single crystals of the uniaxial
    model ferroelectric lithium niobate (LiNbO3; LNO) have been shown to reach resistances
    more than 10 orders of magnitude lower than the resistance of the surrounding
    bulk, with charge carriers being firmly confined to sheets with a width of a few
    nanometers. LNO is thus currently witnessing increased attention because of its
    potential in the design of room-temperature nanoelectronic circuits and devices
    based on such CDWs. In this context, the reliable determination of the fundamental
    transport parameters of LNO CDWs, in particular the 2D charge carrier density
    n2D and the Hall mobility μH of the majority carriers, is of great interest. In
    this contribution, we present and apply a robust and easy-to-prepare Hall-effect
    measurement setup by adapting the standard four-probe van der Pauw method to contact
    a single, hexagonally shaped domain wall that fully penetrates the 200-μm-thick
    LNO bulk single crystal. We then determine n2D and μH for a set of external magnetic
    fields B and prove the expected cosinelike angular dependence of the Hall voltage.
    Lastly, we present photoinduced-Hall-effect measurements of one and the same DW,
    by determining the impact of super-band-gap illumination on n2D.@eng
