| Abstract | We present the electrical characterization of crossbar ionic nanoscale devices built using surfactant coated single walled carbon nanotubes (SWCNTs) via micro contact printing. These electro-ionic building blocks were synthesized by doping intrinsic semi conducting SWCNT doped with surfactant molecules, thereby altering the Fermi energy levels of SWCNTs and their electrical properties. The surfaces of these SWCNTs, were modified by two types of surfactants; sodium docedyl sulfate and cetyl trimethylammonium bromide, to produced anionic SWCNT (P-type) and cationic SWCNT (N-type) respectively. Using dual micro-patterning process, anionic and cationic SWCNT ionic blocks were alternatively symmetrically patterned into a parallel array to form crossbar p-n junctions. Functionality of the nanodevices was demonstrated by studying the current – voltage (I-V) characteristics that shows promise towards the formation of nanoelectronic diode arrays. |
