Abstract: Vertically Oriented Carbon (VOC), a novel material discovered that have many amazing properties. Although the exploration and discovery of the characteristics of this novel material is still at its infancy stage, research has shown that it is the strongest two-dimensional structure known. Not only is VOC thermally and acoustically conductive, its hexagonal crystalline structure allows it to conduct current effectively anisotropic, which is along its plane. With the ability of having extensive applications possibilities and minute information about the electrical characteristic, this report is crafted to help in the research field of its electrical properties. The distinction that set this report apart from others is that instead of having just one sample of the same thickness, this final year project not just only compares but also experiment with VOC of different thicknesses. Experiments are first carry out on different amorphous carbon samples. The results are then compared with different ratios of the vertically oriented carbon samples. With the comparison and distinction being documented and analysed, characterisation of the carbons sample are being done. With two methods of creating VOC documented in this report, the creation of VOC via thermal energy and ion energy, the method chosen to grow thicker VOC film is through ion energy. This is because the adhesion of the VOC on the substrate is stronger via ion energy, when compared with VOC created via thermal energy. This allows much thicker carbon films to be created. This stronger adhesive power provides opportunity to characterise VOC of thicker films. Due to the rapid advancement of technology, suggestions and recommendations of future works are also given in this report. Although much work is to be done in the field of electrical characterisation for the novel vertically oriented carbon, this report has successfully shown the electrical capabilities of this novel material while comparing it with different forms of carbon.
