چکیده
Materials having an anisotropic crystal structure often exhibit anisotropy in the electrical conductivity. Compared to complex transition-metal oxides (TMOs), simple TMOs rarely show large anisotro...

Electrical conductivity of poly(3,4-ethylenedioxythiophene):p-toluene sulfonate films hybridized with reduced graphene oxide
Reduced graphene oxide-poly(3,4-ethylenedioxythiophene):p-toluene sulfonate (rGO-PEDOT:PTS) hybrid electrode films were synthesized directly on a substrate by interfacial polymerization between an oxidizing solid layer and liquid droplets of 3,4-ethylenedioxythiophene (EDOT) produced by electrospraying. The EDOT reduced the graphene oxide by donating electrons during its transformation into PED...
متن کاملEffect of Bismuth Oxide on the Microstructure and Electrical Conductivity of Yttria Stabilized Zirconia
Bismuth oxide (Bi2O3)-doped yttria-stabilized zirconia (YSZ) were prepared via the solid state reaction method. X-ray diffraction and electron diffraction spectroscopy results indicate that doping with 2 mol% Bi2O3 and adding 10 mol% yttria result in a stable zirconia cubic phase. Adding Bi2O3 as a dopant increases the density of zirconia to above 96%, while reducing its normal sintering temper...
متن کاملAtomic layer deposition of Zn(O,S) thin films with tunable electrical properties by oxygen annealing
Zinc oxysulfide, Zn(O,S), films grown by atomic layer deposition were annealed in oxygen to adjust the carrier concentration. The electron carrier concentration of Zn(O,S) can be reduced by several orders of magnitude from 10 to 10 cm 3 by post-deposition annealing in oxygen at temperatures from 200 C to 290 C. In the case of Zn(O,S) with S/Zn1⁄4 0.37, despite the considerable change in the ele...
متن کاملImproved electrical conductivity of graphene films integrated with metal nanowires.
Polycrystalline graphene grown by chemical vapor deposition (CVD) on metals and transferred onto arbitrary substrates has line defects and disruptions such as wrinkles, ripples, and folding that adversely affect graphene transport properties through the scattering of the charge carriers. It is found that graphene assembled with metal nanowires (NWs) dramatically decreases the resistance of grap...

and the cross-plane thermal conductivity K ⊥ ≈ 20 W m −1 K −1 at room temperature (RT). [ 2,3 ] Despite its large K and K / K ⊥ ≈ 100, unprocessed graphite cannot be used for thermal management because it does not meet industry requirements, e.g., fl exibility. The commercial thermal pads based on composites with chemically processed graphite have lower K and smaller K / K ⊥ ratios. These consi...
