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) SrTiO(3) substrates. Individual single crystal MgO nanobelt segments comprising the nanofence have a square cross-section with dimensions in the range of 10-20 nm and with lengths in the range from 100 nm up to 1 microm. X-ray diffraction shows that the 3D MgO nanofence has an epitaxial relation with (100) SrTiO(3) substrates with a cube-on-cube, {100}100 orientation and with values of the full width at half-maximum of the (200) omega-scan and the (110) varphi-scan at 4.5 degrees and 5.5 degrees , 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.
