Carbon nanotubes and the pursuit of the ultimate body …
2010/8/6· Alumina, silicon carbide and boron carbide are some of the candidate ceramic materials commonly used in body armor. Although these ceramics are very hard, they are also quite brittle and, therefore, hardly able to survive one or two shots before astrophic fracture of the ceramic tile leading to collateral damage.
How Do CNTFETs Work, and Why Are They So Promising? …
2020/7/17· A CNTFET is a nano-scaled device that can provide low-power integrated circuits with high performance and high power density. Instead of the bulk silicon material used in traditional metal-oxide semiconductor field-effect transistors (MOSFETs), CNTFETs use carbon nanotubes (CNTs) in between the source and the drain of a MOSFET structure.

2012/2/29· In 2006, Garcia et al. reported the first PECVD amorphous silicon carbide TFTs. The a-Si 1-x C x :H films were deposited on glass substrates by PECVD at 300ºC using SiH 4 /CH 4 /H 2 gas mixture. Subsequently, n-type a-Si:H layer was deposited using SiH 4 /H 2 /PH 3 gas mixture and a photolithography was performed.
