Polar-surface dominated ZnO nanobelts and the electrostatic energy induced nanohelixes, nanosprings, and nanospirals
(Georgia Institute of Technology, 2004-02-09)
We report the controlled synthesis of free-standing ZnO nanobelts whose surfaces are dominated by the large polar surfaces. The nanobelts grow along the a axis, their large top/bottom surfaces are the ±(0001) polar planes, ...
Controlled synthesis and manipulation of ZnO nanorings and nanobows
(Georgia Institute of Technology, 2005-01-19)
An experimental procedure is presented for the controlled synthesis and manipulation of ZnO nanorings and nanobows at high purity and large yield. Atomic force microscopy manipulation of the nanostructures demonstrates ...
Nanoscale mechanical behavior of individual semiconducting nanobelts
(Georgia Institute of Technology, 2003-08-04)
Nanobelts are a group of materials that have a rectangle-like cross section with typical widths of several hundred nanometers, width-to-thickness ratios of 5–10, and lengths of hundreds of micrometers. In this letter, ...
Nanoarchitectures of semiconducting and piezoelectric zinc oxide
(Georgia Institute of Technology, 2005-01-21)
Semiconducting and piezoelectric zinc oxide has two important structure characteristics: the multiple and switchable growth directions: 010, 20, and 0001; and the {0001} polar surfaces. The fast growth directions create ...
