Although CNT sensors have been shown to be highly sensitive to certain analytes, a long-standing barrier to the introduction of ultra-sensitive CNT sensors has been a lack of selectivity. Functionalized semiconducting CNT arrays, which are capable of distinguishing explosives from common background gases, distinguishing nitroaromatic from nitramine explosives, and discriminating among different nitramine explosives with very similar designs, according to Ab initio studies of functionalized semiconducting CNT arrays, capable of distinguishing explosives from common background gases, distinguishing nitroaromatic from nitramine explosives, identifying nitramine explosives.
The excitation and interband plasmon resonances are closer together for homogeneous single-chirality CN films, as the intertube coupling and thermal broadening bring the exciton and interband plasmon resonances closer together. We also show that for a properly fabricated two-component CN film, one can adjust the optical absorption profile to make the film transmit or absorb light in the neighborhood of an exciton absorption resonance on demand.
Because of their high mobility and low-cost processing, carbon nanotubes are the most suitable candidates for beyond-silicon nano-electronics. For advanced CNT electronics, fabrication of n-type behavior field effect transistors based on assembled aligned CNT arrays is required. We present a scalable method to make n-type behavior FETs based on assembled aligned CNT arrays here in this paper. High yield is achieved by combining the atomic layer deposition dielectric and metal contact engineering, resulting in high yield. CNT FETs are produced with high yield by air-stable and high-performance n-type conductivity. Additionally, we also investigated the effect of metal contacts and atomic layer deposition passivation in determining transistor polarity.
This work experimentally investigated the water droplet impingement behavior on carbon nanotube array surfaces with varying wettabilities ranging from hydrophilicity to superhydrophobicity. Six typical dynamic behaviors of droplet impact were identified, six common droplet effect patterns were identified, and a related droplet regime map was created under various wettabilities, with different wettabilities. At the initial stage of spreading, the contact line velocity in the vicinity of a triple phase interface was found to be highly similar to the DCA variation.
Both fundamental and technological importance for their applications in LC adaptive lenses, low voltage LC displays, smart windows, and many others are among the many other areas that can be used in LC adaptive lenses, Hybrid-aligned nematic liquid crystal devices. On one side of the LC cell, we report the manufacturing and characterization of a nanostructure-based HAN device with vertically aligned carbon nanotube arrays as the homeotropic alignment agent and two-dimensional hexagonal boron nitride as the planar alignment agent. The LC achieves a homeotropic state as the LC's applied electric field ramps up across this VA-CNT/h HAN cell, but without a threshold voltage to begin the reorientation process; this result is similar to that of a conventional polyimide-based HAN cell; this behavior is similar to that of a traditional polyimide-based HAN cell. This report shows that two inorganic nanostructured surfaces, VA-CNT arrays and 2D h -BN, can quickly replace the organic PI alignment agents when required while still maintaining the HAN device's essential electro-optical results.
Until now, periodic vertically aligned carbon nanotube array assembly growth was largely dependent on at least one lithography step during manufacturing. The MWCNTs are synthesized by plasma enhanced chemical vapor deposition from Ni catalyst particles. Template guided dewetting of a thin Ni film on a hexagonally close-packed silica particle monolayer provides regular Ni catalyst particles as seeds for the development of periodic MWCNT arrays. Individual MWCNTs can also be adjusted, depending on the Ni particle size and PECVD time.
