Multiwall carbon nanotubes (CNTs) were grown by the plasma-enhanced chemical vapor deposition (PECVD) method in downstream on the p-Si (100) substrate.
Multiwall carbon nanotubes (MWCNTs) were grown by dielectric barrier discharge (DBD)-type plasma enhanced chemical vapor deposition (PECVD) method in downstream.
As supersonic speed at upper reaches and subsonic speed at lower reaches in a duct, the position of shock layer is analyzed and the asymptotic estimation of solution, is obtained.
