Electrical Properties of Defects in Carbon Nanotubes Brett Goldsmith UC Irvine Department of Physics and Astronomy Collins Group
SPM Studies of Nanotubes There have been a number of studies to characterize the frequency and effects of defects in nanotubes. Some unanswered questions still remain: –Is gate dependence only based on band structure? –Are high resistance devices always dominated by contact effects? Freitag et al, PRL 89 (21) 2002
Summary metallic nanotubes can have local gate dependence gate sensitive regions correspond to points of local voltage drops Dr. Phil Collins Dr. Yuwei Fan Nathan Emmott Derek Kingrey Alex Kane Bucky Khalap Jorge Guerra Kevin Loutherback ACS-PRF
