A simple and controlled method to fabricate a 3D, epitaxial, biaxially textured nanofence comprised of single crystalline MgO nanobelt segments or links that grew both vertically and horizontally along <100> directions of the (100) STO substrate was developed. Continuous supply of Ni catalyst during the co-laser ablation of MgO and Ni metal led to the growth of nanobelts with such a unique morphology. Individual single crystalline MgO nanobelts had a square cross-section with high aspect ratios. X-ray diffraction results obtained from an entire MgO nanofence layer confirmed that MgO nanofence had epitaxial relation with STO substrate of [100]MgO∥︀[100]STO. Such oxide nanofences can be used as a 3D biaxially-textured nanotemplate for epitaxial growth of wide-ranging, 3D, electronic, magnetic and electromagnetic nanodevices.
