      abstract     = {The great variability in the electrical properties of
                      multinary oxide materials, ranging from insulating, through
                      semiconducting to metallic behaviour, has given rise to the
                      idea of modulating the electronic properties on a nanometre
                      scale for high-density electronic memory devices. A
                      particularly promising aspect seems to be the ability of
                      perovskites to provide bistable switching of the conductance
                      between non-metallic and metallic behaviour by the
                      application of an appropriate electric field. Here we
                      demonstrate that the switching behaviour is an intrinsic
                      feature of naturally occurring dislocations in single
                      crystals of a prototypical ternary oxide, SrTiO(3). The
                      phenomenon is shown to originate from local modulations of
                      the oxygen content and to be related to the self-doping
                      capability of the early transition metal oxides. Our results
                      show that extended defects, such as dislocations, can act as
                      bistable nanowires and hold technological promise for
                      terabit memory devices.},
