Abstract:The paper presents an evaluation of the feasibility of developing ionic surfactant coated single walled carbon nanotube (SWCNTs) (P-N) junction clusters via microcontact printing using intrinsic semi conducting SWCNTs. These SWCNTs are doped with anionic and cationic surfactant molecules respectively, thereby altering the Fermi energy levels of and its electrical properties. Two types of surfactants were used for doping the SWCNTs to develop extrinsically doped P and N type SWCNTs. Sodium dodecyl sulfate (SDS)… Show more
