We investigated the influence of deposition time and thickness on the transparent conducting characteristics: conductivity, sheet resistance, and transparency, of graphene films.
Moreover, while the rGO sample with 50%% coverage is non-conducting near zero bias, it seems to show conducting characteristics as the applied voltage increases.
For the majority of films, DC conductivity measurements over the range 77 300 K showed an increase in the conductivity with increasing temperature, i.e. semi-conducting characteristics.
Finally, the conducting characteristics of the graphene films were evaluated by Hall effect measurement HMS-30000, EcopiAnyangang, South Korea).
The calculated results show that boron substitutional doping changes the conducting characteristics of GNRs to half-metallic.
According to [21], rGO with 25%% coverage is expected to have conducting characteristics around zero-bias and the transmission spectrum shown in Fig. 4d supports this.
We present a study on the transparent conducting characteristics of graphene-based films prepared by means of rapid chemical vapor deposition.
Since the solid electrolyte shows considerable high ion-conducting characteristics, promising applications like rechargeable batteries and chemical sensors for an environmental gas monitoring are greatly expected.
This network polymer was confirmed to have cation conducting characteristics, since a constant current was observed in dc polarization studies with lithium metal as an active electrode.
The first observation considering these I V characteristics is that at zero-bias; rGO with 50%% coverage shows non-conducting characteristics, while rGO samples with coverage ratios of 25%% and lower clearly show conducting characteristics as shown inside the circle.
