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, ...
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 ...
