Abstract
A method for transferring a carbon nanotube array is provided. A substitute substrate, a growing substrate, and a carbon nanotube array grown on the growing substrate are provided. The carbon nanotube array has a bottom surface adjacent to the growing substrate and a top surface away from the growing substrate. The substitute substrate is placed on the top surface of the carbon nanotube array and liquid medium is sandwiched between the substitute substrate and the carbon nanotube array. The liquid medium is solidified between the substitute substrate and the carbon nanotube array. The substitute substrate is separated from the growing substrate to separate the bottom surface of the carbon nanotube array from the growing substrate. The solid medium is removed between the substitute substrate and the carbon nanotube array. A method for forming a carbon nanotube structure is also provided.
