Diameter Modulation by Fast Temperature Control in Laser-assisted Chemical Vapor Deposition of Single-walled Carbon Nanotubes

On the Cover: Diameter modulation of single-walled carbon nanotubes (SWNTs) in different segments was successfully achieved by fast temperature control in laser-assisted chemical vapor deposition (LCVD). Due to the inverse relationship between the SWNT diameter and the growth temperature, SWNTs with ascending diameters were obtained by reducing the LCVD temperature from high to low. The diameter-modulated SWNTs were integrated in electrodes to form field-effect transistors (FETs) and to investigate their electronic transport properties.
