Abstract: A method for fabricating a hollow nanotube structure is disclosed. The method includes the steps of providing a substrate, developing a plurality of nanowires on the substrate with a predetermined size on the seed layer at relatively low temperature by a hydro-thermal growth method, forming an outer covering layer on the surfaces of the nanowires, selectively etching an upper end of the outer coating layer to expose an upper end of the nanowires and removing the nanowires to remain the hollow outer coating layer to form a plurality of hollow nanotubes. The method can simplify the nanotube manufacturing process, increase the dimension precision of the nanotubes and enhance the photoelectric properties of micro-electro-mechanical elements.
