2D‐TEM investigations of CNT s synthetized within vertical‐PAA templates for devices applications

摘要: Since their discovery in 1991 carbon nanotubes (CNTs) become one of the most emblematic type of nanostructures due to their unique electrical, mechanical, thermal and optical properties. Despite these promising and astonishing properties, the critical subject of their manipulation remains a primordial challenge. Very expensive and time consuming techniques, like e‐beam lithography, have been developed in order to precisely control their growth, or to obtain a nano‐object from the etching of a bulk material. Such techniques are suitable as proofs of concept; however the object‐by‐object manipulation approach is unrealistic because they are not compatible with a massive integration. On the other hand the miniaturization of the fabricated devices is reaching a bottleneck since the scaling‐down for enhancing their performance is approaching many physical limitations. The efforts concentrated to achieve device …
