The electronic properties of DWs can be tuned by the application of strain, hence controlling the charge carrier density at DWs. In this paper, we study the influence of uniaxial stress on the conductivity of DWs in the bulk single crystal lithium niobate (LiNbO3). Using conductive atomic force microscopy, we observe a large asymmetry in the conductivity of DWs, where only negatively screened walls, so called head-to-head DWs, are becoming increasingly conductive, while positively screened, tail-to-tails DWs, show a decrease in conductivity. This asymmetry of DW conductivity agrees with our theoretical model based on the piezoelectric effect. In addition, we observed that the current in the DW increases up to an order of magnitude for smaller compressive stresses of 100 MPa. This response of DWs remained intact for multiple stress cycles over two months, opening a path for future applications.}}, author = {{Singh, Ekta and Beccard, Henrik and Amber, Zeeshan H. and Ratzenberger, Julius and Hicks, Clifford W. and Rüsing, Michael and Eng, Lukas M.}}, issn = {{2469-9950}}, journal = {{Physical Review B}}, number = {{14}}, publisher = {{American Physical Society (APS)}}, title = {{{Tuning domain wall conductivity in bulk lithium niobate by uniaxial stress}}}, doi = {{10.1103/physrevb.106.144103}}, volume = {{106}}, year = {{2022}}, } @article{21094, author = {{Aldahhak, Hazem and Hogan, Conor and Lindner, Susi and Appelfeller, Stephan and Eisele, Holger and Schmidt, Wolf Gero and Dähne, Mario and Gerstmann, Uwe and Franz, Martin}}, issn = {{2469-9950}}, journal = {{Physical Review B}}, title = {{{Electronic structure of the Si(111)3×3R30°−B surface from theory and photoemission spectroscopy}}}, doi = {{10.1103/physrevb.103.035303}}, year = {{2021}}, } @article{22214, author = {{Mund, Johannes and Yakovlev, Dmitri R. and Sadofev, Sergey and Meier, Cedrik and Bayer, Manfred}}, issn = {{2469-9950}}, journal = {{Physical Review B}}, title = {{{Second harmonic generation on excitons in ZnO/(Zn,Mg)O quantum wells with built-in electric fields}}}, doi = {{10.1103/physrevb.103.195311}}, volume = {{103}}, year = {{2021}}, } @article{23477, author = {{Thong, Le Huu and Ngo, Cong and Duc, Huynh Thanh and Song, Xiaohong and Meier, Torsten}}, issn = {{2469-9950}}, journal = {{Physical Review B}}, pages = {{085201}}, title = {{{Microscopic analysis of high harmonic generation in semiconductors with degenerate bands}}}, doi = {{10.1103/physrevb.103.085201}}, volume = {{103}}, year = {{2021}}, } @article{29749, author = {{Murzakhanov, F.
