WebNov 3, 2024 · Carbon nanotube (CNT) photonics is an emerging field with fascinating properties 1,2,3,4.It offers a challenge to both fundamental and applied sciences. WebMay 23, 2024 · Apart from diameter and chirality of CNT, other physical parameters that affect the drain current are contact between CNT and source/drain (S/D), gate dielectric material, channel length, and thickness of gate dielectric . It was observed that a small diameter of CNT leads to high value of leakage current which in turn reduces the mobility.
WebA vector connecting the centers of the two hexagons is called the chiral vector, and it determines the structure of a single-walled carbon nanotube. A chiral vector C can be specified by a chiral index (n,m) using basis … WebFor sensing applications, semiconducting CNTs (s-CNTs) are often preferred. The production of highly pure CNTs in terms of chirality is therefore key to CNT sensing applications. CNTs with a low chiral distribution can be synthesized by direct growth methods or postsynthesis purification.
