Ultrahigh carrier mobilities in ferroelectric domain wall corbino cones at room temperature

HIGHLIGHTS

SUMMARY

    To mobility, the authors also infer the carrier density to be a small fraction of that required for screening the polar discontinuity at the wall, and this indicates, as has been seen in other domain wall systems,[31,32] that the overwhelming majority of assumed screening charges do not participate in conduction. www.advmat.de 3. The expected resistance change might only be of the order of 1% or less, depending on the carrier mobility. The current response (averaged over 20 cycles) is plotted in Figure 3a along with the magnetic_field profile used. A . . .
