Claim Text:
1. A method for making an epitaxial structure, the method comprising: providing a free standing carbon nanotube film, wherein the carbon nanotube film comprises a plurality of carbon nanotubes orderly arranged and combined with each other via van der Waals force to form a plurality of apertures; inducing defects on surfaces of the plurality of carbon nanotubes to form a treated carbon nanotube film; growing a nano-material layer on the surfaces of the plurality of carbon nanotubes by atomic layer deposition to form a nanotube film preform; obtaining a free-standing nanotube film by removing the carbon nanotube film by annealing the nanotube film preform, wherein nanotube film comprises a plurality of nanotubes orderly arranged and combined with each other; placing the nanotube film on an epitaxial growth surface of a substrate; and epitaxially growing an epitaxial layer on the epitaxial growth surface of the substrate.
