Ab initio study of CNT NO2 gas sensor

Selective dispersion of high purity semiconducting single-walled carbon nanotubes with regioregular poly(3-alkylthiophene)s

“…3; Supplementary Figs S8, S9) to further determine the different chiralities of SWNTs dispersed with rr-P3DDT, and compared it with SWNTs dispersed with sodium dodecyl sulphate (SDS; which has been previously reported to not show any selective sorting) 42 . As the PLE data indicate in Figure 3, the dominant SWNTs dispersed with rr-P3DDT were (12,1), (10,5), (8,6), (9,4) and (9,5). On the other hand, SDS/water dispersed a wide variety of SWNTs (Supplementary Figs S8, S9).…”

“…with an on/off current ratio of ~10 6 were obtained without any 'burn-off ' or posttreatment (Fig. 4b,c).…”

“…S ingle-walled carbon nanotubes (SWNTs) have a wide range of extraordinary mechanical, chemical and electronic properties 1 , making them ideal candidates for various applications, such as composites 2 , energy storage 3 , biological and chemical sensors [4][5][6][7] , flexible electronics 8,9 and transparent electrodes 10,11 . In particular, the high charge-carrier mobility of semiconducting (sc-) SWNTs together with the ability for solution processing hold a great promise for high-performance low-cost transistor applications.…”

Effect of Monovacancy Defects on Adsorbing of CO, CO<sub>2</sub>, NO and NO<sub>2</sub> on Carbon Nanotubes: First Principle Calculations

“…The specific geometry and unique properties of carbon nanotubes suggest important potential applications including transistors, hydrogen storage devices, quantum dots, gas sensors, and so many other applications [2][3][4][5]. Gas adsorption on carbon nanotubes is a great issue for both essential research and applied application of nanotubes.…”

Ab-initio calculations for a realistic sensor: A study of CO sensors based on nitrogen-rich carbon nanotubes

“…6,7 As mentioned above, its one-dimensional character also make it stand out as a candidate for possible gas sensoring applications, [8][9][10][11][12] although it has been demonstrated by theoretical approaches that pristine carbon nanotubes are usually inert to closed shell molecules. 13,14 One promising approach to circumvent this limiting factor is to functionalize them, creating reactive sites where molecules would bind more easily. [15][16][17] Carbon nanotubes with nitrogen atoms incorporated during growth -the so-called CN x nanotubes -fall within this category 18,19 and are possible candidates to address this problem.…”
