The paper presents a study of the field emission properties of a new nanocomposite material based on a mixture of carbon nanotubes and organic substance (valine amino acid). On the surface of a thin composite layer covering an electrically conductive metal cathode there was experimentally revealed a developed network of active electron emission sites. Valine not only enhanced field emission properties of the composite surface, but also acted as a binder thus providing high adhesion and strength of the nanocomposite coating. Keywords: electron field emission, carbon nanotubes, amino acid, valine.
