Research Projects

The display is a crucial human interface in electronic entertainment systems, and the fabrication of conducting cold cathode field-emission FE materials is of particular concern for display applications. One-dimensional 1D nanostructures, such as nanotubes, nanowires, and nanorods, have been chosen as favourable emitter materials for FEE devices due to their quicker device turn-on time, sustainability, and compactness. Various nanostructures from metals, semiconductors, and carbon materials have been developed to achieve better FEE performance. However, carbon nanostructures, such as CNTs, carbon nanosheets, nanodiamonds, and graphene, show enhanced FEE characteristics. Combining different nanoscale carbon materials to synthesize a hybrid material is considered an effective route to achieve enhanced FEE characteristics compared with a single nanocarbon material. This project aims to fabricate nanostructured diamond hybrids (NDHs) for high-performance and long-life cold cathode materials for vacuum microdevices, such as compact X-ray sources, ballistic transistors, ion engines, and novel display and plasma devices. The project will address strategic objectives such as fabrication, characterization, Hall effect measurements, field electron emission, field distribution studies, and plasma illumination measurements.
