A three-dimensional, biaxially textured oxide nanofence composed of MgO single crystal nanobelt segments

A unique, three-dimensional (3D), biaxially textured, MgO, nanofence comprised of single crystal MgO nanobelt segments or links was synthesized via epitaxial growth on (100) SrTiO₃ substrates. Individual single crystal MgO nanobelt segments comprising the nanofence have a square cross-section with dimensions in the range of 10-20nm and with lengths in the range from 100nm up to 1νm. X-ray diffraction shows that the 3D MgO nanofence has an epitaxial relation with (100) SrTiO₃ substrates with a cube-on-cube, {100}〈100〉 orientation and with values of the full width at half-maximum of the (200) ω-scan and the (110) φ-scan at 4.5° and 5.5°, respectively. Such a biaxially textured oxide nanofence with single crystal segments can be used as a 3D nanotemplated substrate for epitaxial growth of wide-ranging, 3D, electronic, magnetic and electromagnetic nanodevices.
