Claim 0:
1. A method of fabricating a covalently reinforced carbon nanotube (CNT) assembly, comprising:
producing a CNT assembly by pulling entangled CNTs from a CNT array fabricated on a substrate, the CNT assembly including a plurality of CNTs that are aligned; and
inducing a high stiffness in the CNT assembly by applying a high energy ion irradiation to the CNT assembly such that an intensity of a D band of Raman spectroscopy of the CNT assembly is greater than an intensity of a G band of the Raman spectroscopy of the CNT assembly, wherein an irradiation cross-section of the high energy ion irradiation is selected such that the ions of the high energy ion irradiation pass through an overall thickness of the CNT assembly to generate defects uniformly without inducing ion implantation.
