27‐2: Field Emission Beyond Information Displays

Field emission is at the heart of a wide range of research areas and technologies. The commercialisation of some of these technologies has been limited due to the challenges to achieve emission uniformity, yield, and lifetime within the tolerances that the industry demands. The recent advances in simulation tools and nanofabrication have enabled the effective design and production of field emitter enabled technologies. Here, we present the construction, functionalities, and limitations of our computational tool for field emission design and analysis, along with relevant examples ranging from 3D portable medical imaging to novel cancer therapy.
