Amorphous Carbon Layer

The high-capacity of Nb2O5 nanosheets has been successfully realized through introducing amorphous carbon layers, which have been demonstrated to have a large capacity owing to the existence of defects on amorphous carbon layers.

Amorphous Carbon Layer

ABSTRACTDiamond films prepared by microwave plasma chemical vapor deposition, using a gas mixture of methane and hydrogen with ethanol, were formed on silicon substrates. Highresolution transmission electron microscopy was employed to characterize the microstructure at interface regions. It was found that the diamond crystals were grown on an amorphous carbon layer. Twins and stacking faults were observed at the regions interfaced with the amorphous carbon layer, suggesting that the defects may already exist in the nucleation stage and at the very first stage of growth. Also, some diamond nuclei embedded in the amorphous layer were observed.

Structure of amorphous carbon can be composed of sp2 (graphite), or sp3 (diamond), or a combination of both, depending on their fractions. Therefore, many researchers were exploring to use it as solar cell material. This research used the amorphous carbon of bio-product as a basic material in the form of palmyra sugar which was synthesized through the heating and doping process to produce n-type and p-type semiconductors. This research aims to analyze the effect of dopant and deposition time on electrical properties. The heating process was carried out at 250°C and the doping process was carried out by adding NH4OH for a-C:N and H3BO3 for a-C:B. The deposition process was carried out by the nano-spray method using a variety of deposition time on the ITO substrate. The result of scanning electron microscopy (SEM) showed that the film thickness increased with the increase of deposition time. Besides, the result of four-point probe (FPP) showed that the dopant can increase electrical conductivity, but the film thickness did not influence it. The electrical conductivity obtained was 5x10-1 - 6x10-1 S/cm. And the result of further analysis, it can be concluded that electrical conductivity was still in the range of semiconducting material.

Amorphous Carbon Layer

The recent discovery of graphite cones [1,2] has raised some interesting questions about the nucleation and growth of curved graphitic structures. Here we report the structural peculiarities of one member of the ensemble, i.e. the flat graphite disks. Unlike graphite flakes seen in carbon soot which are irregularly shaped, the disks in this sample often show regular faceting which might give us additional insight into the growth mechanisms.The samples were examined in a Hitachi H9000 NAR TEM. Samples were sonicated in high purity methanol and dispersed on a 300 mesh Cu grid coated with a 20 nm thick amorphous carbon layer. Typical disk diameters range from 0.5 to 3.0 μm, with thickness ranging from 10 nm to 50 nm.A close examination reveals that the edges of the disks are faceted and typically have 12 sides. In most cases, the edges show a long facet alternating with a shorter facet.
