ABSTRACT
A method is presented where the morphology of screen printed carbon nanotube pastes is modified using an adhesive tape. In this way, the organic matrix material is preferentially removed leaving an optimal emitter surface of sparsely distributed and well-aligned carbon nanotubes. From these emitter surfaces, homogeneous emission was observed with emitter site densities of at least 10[sup 4] emitters cm[sup -2] and extracted current densities over 500 mA cm[sup -2]. © 2003 American Institute of Physics.
