Abstract

The proposed project is concerned with the characterisation of large area cathodes for application in field emitter displays. Our main intentions are two fold. It is well known that flat cathode materials often have to under go a conditioning phase in order to initiate electron emission. Firstly, we wish to develop ways which can be used to efficiently activate cold cathode materials at a macroscopic level in order to produce controllable and uniform emission over the cathode surface. This will be done by the means of current induced conditioning. In parallel to this we wish to understand at a nanometer level what are the microstructural changes that occur in these cathodes during conditioning and emission using some of the recently installed state of the art analysis equipment at the University of Surrey through the Advanced Technology Institute.

In this manner through a comprehensive understanding at the nanometer level of the conditioning and emission processes can be obtained which will applicable to engineer cathode systems effectively. We also wish to investigate the low temperature growth of carbon nanotubes and the subsequent use in as a field emission cathode.
