using c2h2, 112 and as gases at 550'c, carbon nanotubes were fabricated on the surfaces of twosubstrates coated by nano thin layers of metal catalysts by dc magnetron sputtering. aystamless steel andfe/cteal, by thermal chemical vapor deposition (tcvd) the surface properties of the substrates wereparticularly investigated, and the effect of treatment of the substrates on the cnt's growth is cri...
the current study reports some interesting growth of novel in2o3 nanostructures using ambient-controlled chemical vapor deposition technique in the presence of a strongly reducing hydrazine ambient. the experiments are systematically carried out by keeping either of the carrier gas flow rate or the source temperature constant, and varying the other. for each of the depositions, the growth is st...
Thermodynamic analysis of the chemical vapor deposition (CVD) of P3N5 has been performed using the method of the minimization of the Gibbs' free energy in order to evaluate the pH3-NH -N , PCI3-NH3-H2 and PBr3-NH3-H2 gaseous mixtures for their 3. 2 potential to synthesize slngle-phase P N films at high yields. The conditions for the 3 5 deposition of P3N5 have been determined as a function of i...
Silica core-shell nanoparticles of about 60-120 nm with a closed outer layer of bismuth or molybdenum oxide of 1-10 nm were synthesized by an integrated chemical vapor synthesis/chemical vapor deposition process at atmospheric pressure. Film growth rates and activation energies were derived from transmission electron microscopy (TEM) images for a deposition process based on molybdenum hexacarbo...
High-quality large-sized hexagoal WSe2 crystals can be grown on dielectric substrates using atmospheric chemical vapor deposition in the presence of hydrogen gas. These hexagonal crystals (lateral width >160 um) have a carrier mobility of 100 cm(2) V(-1) s(-1) and a photoresponsivity of ≈1100 mA W(-1), which is comparable to that of exfoliated flakes.
