  bibo_abstract:
  - In the last two decades, variably doped strontium barium niobate (SBN) has attracted
    a lot of scientific interest mainly due to its specific non-linear optical response.
    Comparably, the parental compound, i.e., undoped SBN, appears to be less studied
    so far. Here, two different cuts of single-crystalline nominally pure strontium
    barium niobate in the composition Sr0.61Ba0.39Nb2O6 (SBN61) are comprehensively
    studied and analyzed with regard to their photoconductive responses. We present
    conductance measurements under systematically varied illumination conditions along
    either the polar z-axis or perpendicular to it (x-cut). Apart from a pronounced
    photoconductance (PC) already under daylight and a large effect upon super-bandgap
    illumination in general, we observe (i) distinct spectral features when sweeping
    the excitation wavelength over the sub-bandgap region as then discussed in the
    context of deep and shallow trap states, (ii) extremely slow long-term relaxation
    for both light-on and light-off transients in the range of hours and days, (iii)
    a critical dependence of the photoresponse on the pre-illumination history of
    the sample, and (iv) a current–voltage hysteresis depending on both the illumination
    and the electrical-measurement conditions in a complex manner.@eng
