Abstract
A method for making a carbon nanotube array includes providing a substrate having a first substrate surface and a second substrate surface opposite to the first substrate surface. The substrate has a plurality of through holes spaced from each other, and each of the plurality of through holes extends from the first substrate surface to the second substrate surface. A catalyst layer is deposited on the first substrate surface, to form a composite structure. The composite structure is placed in a chamber. The carbon source gas and protective gas are supplied to the chamber, and the composite structure is heated to a first temperature, to grow a carbon nanotube array on the first substrate surface.
