METHOD FOR MANUFACTURING NANOTUBE OF PIEZOELECTRIC MATERIAL AND NANOTUBE OF PIEZOELECTRIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing nanotubes from nanorods by selectively etching only inner parts of nanorods of a piezoelectric material having an asymmetric crystal structure, and to provide nanotubes of the piezoelectric material. SOLUTION: Nanotubes are manufactured by supplying hydroxide ions to nanorods of the piezoelectric material having the asymmetric crystal structure so as to etch inner parts of the nanorods. For example, inner parts of nanorods is selectively etched by bringing nanorods of the piezoelectric material having the asymmetric crystal structure into contact with a basic solution that generates hydroxide ions. The inner parts of the nanotubes thus prepared do not have growth faces formed by growing nanotubes but have etched faces formed by etching. COPYRIGHT: (C)2010,JPO&INPIT
