Grad Seminar: "CNT-based Field Electron Emission"
Abstract
With an increasing demand for better medical diagnostic systems, improving the efficiency and effectiveness of medical diagnostics have never been more crucial. Field electron emission (FE) based X-ray source which is a more responsive and controllable alternative to traditional thermionic-emission-based X-ray sources has stimulated much research interest. Among the materials for FE, carbon nanotube (CNT) is one of the most promising candidates due to exceptional properties such as a high aspect ratio and good electrical and thermal conductivities.
