Patterning colloidal metal nanoparticles for controlled growth of carbon nanotubes
Single-walled carbon-nanotube (SWCNT) arrays are generated on catalyst patterns with controlled location, orientation, and spacing using a straightforward approach. Dip-pen nanolithography is used to fabricate catalyst ...
Template-directed growth of nanostructures
The controlled growth and alignment of carbon nanotubes and peptide nanoarrays offers new avenues for nanodevice fabrication. Creating intricate nanoelectronic devices requires the precise patterning of carbon nanotube ...
Controlled growth of peptide nanoarrays on Si/SiOx substrates
PAMAM dendrimer nanopatterns on Si/ SiOx substrates generated by dip-pen nanolithography are used as anchoring scaffolds for the growth of peptides in situ by ring-opening polymerization of tryptophan-N-carboxyanhydrides. ...
Charge injection at carbon nanotube-SiO2 interface
Most single-wall carbon nanotube field-effect transistors show significant hysteresis in their transfer characteristics between forward and reverse gate bias sweeps. It was proposed that the hysteresis is due to a dynamic ...
