In order to help unravel the mysteries surrounding the superconducting and pseudogap states in the
high-Tc cuprates, we have measured the electronic transport properties of underdoped, high-Tc nanowires
and nanostructures. The sizes of the samples involved allow for the investigation of the electronic structure
on a mesoscopic length scale. We have measured current-voltage characteristics, resistivity, and critical
current density all as a function of temperature, width, and orientation relative to the crystal axes. The
resistivity displays large fluctuations within a temperature regime from Tc to 200K, and the currentvoltage
characteristics exhibit hysteretic steps. These features are difficult to explain within the context of
known models and may indicate the presence of intrinsic inhomogeneities, charge stripes, or other electronic
domain structures that have been proposed for the cuprates.
