present the synthesis of the high quality single walled carbon nanotubes
(SWCNT) as well as discuss their formation mechanisms during floating catalyst
CVD synthesis from CO at ambient pressure and at temperature range 800-1100 oC
using iron nanoparticle catalyst. We discuss the effect of reactor
operating temperature on the individual tube as well as bundle length and their
diameter distributions, being determined both by electron microscopic as well
as optical methods. Especially, we discuss the control of tube chirality
distributions via introducing trace amounts of CO2 and NH3 into the reactor.
Also, we present the novel nanocarbon material, carbon nanobud (CNB), combining
fullerene molecules covalently bonded onto the outer surface of SWCNTs. We
present recent findings to use ALD-deposited mono and bi-metallic catalysts for
the low temperature CVD synthesis of narrow chirality distribution SWCNTs
from CO.<o:p></o:p></span></font></p>

for SWCNT as well as CNB dry deposition at ambient temperature to manufacture
transparent thin conductors, cold electron field emitters, sensors and field
effect transistor (TFT) with high carrier mobility as compared to organic
semiconductors as well as transparent and flexible thin film conducting
electrodes (TCE). These methods are based on floating catalyst, high
temperature CVD synthesis of high quality SWCNTs from CO using Fe nanoparticle
catalyst followed by SWCNT ambient temperature, direct, dry deposition onto the
substrate. Flexible SWCNT-PET conducting films show transparency-sheet
resistance properties similar to ITO-PET films. SWCNT network TFTs on
both silicon as well as polymeric substrates exhibit mobilities above 20
cm2/Vs and on/off ratio of 106.<o:p></o:p></span></font></p>
