Strain-induced formation of K{sub 2}Ti{sub 6}O{sub 13} nanowires via ion exchange
- Beijing Laboratory of Electron Microscopy, Institute of Physics, P.O. Box 603, Chinese Academy of Sciences (China)
Nanowires with 10 nm in diameter and several microns in length have been synthesized by ion exchange reaction of Na{sub 2}Ti{sub 3}O{sub 7} in KOH aqueous solution, and the structure of these nanowires has been determined to be K{sub 2}Ti{sub 6}O{sub 13}. It was shown that the nanowires were formed as a result of strain induced phase transformation from the Na{sub 2}Ti{sub 3}O{sub 7} structure to K{sub 2}Ti{sub 6}O{sub 13}. The length of the nanowires was determined largely by the size of the raw Na{sub 2}Ti{sub 3}O{sub 7} crystal along its [010] direction, and the cross section was determined mainly by the competition between the lattice misfit resulted strain energy and the bonding characteristics of the Na{sub 2}Ti{sub 3}O{sub 7} structure.
