Abstract :
Carbon nanotubes (CNTs) were grown by two different methods. The catalytic growth on a silicon wafer showed ultra high aspect ratios for the CNTs with extremely high field enhancement coefficients >25000 and a turn-on field of 0.36 V/μm, whereas the non-catalytic growth resulted in substrateless flexible CNT bundles with a simple gate electrode integration process. Results on an additional coating of the CNT emitter with ZnO with modified field-emission characteristics will be presented.
