Iacobucci, S and Fratini, M and Rizzo, A and Scarinci, F and Zhang, Y and Mann, M and Li, C and Milne, WI and El Gomati, MM and Lagomarsino, S and Stefani, G (2012) Angular distribution of field emitted electrons from vertically aligned carbon nanotube arrays. Applied Physics Letters, 100. ISSN 0003-6951Full text not available from this repository.
Angular field emission (FE) properties of vertically aligned carbon nanotube arrays have been measured on samples grown by plasma enhanced chemical vapor deposition and characterized by scanning electron microscope and I-V measurements. These properties determine the angular divergence of electron beams, a crucial parameter in order to obtain high brilliance FE based cathodes. From angular distributions of the electron beam transmitted through extraction grids of different mesh size and by using ray-tracing simulations, the maximum emission angle from carbon nanotube tips has been determined to be about ± 30 around the tube main axis. © 2012 American Institute of Physics.
