In this paper, we present the results of predictive modeling of composites with optimal geometrical parameters for later of their use as the element base of electronic devices. Geometric parameters of the composite are the length and diameter of the nanotubes, as well as the distance between the nanotubes in the composite. Identification of the optimal configuration of the composites was carried out so that the stability and the work function of the composites were increased. It was found that a high emissivity and energy sustainability will have a nanocomposite «CNT-graphene» in which a carbon nanotube has a diameter of 0.5 nm and a length of 0.7 nm at a fixed distance between the nanotubes 3.7 nm. There are now successful synthesis technology composites «CNT-graphene». Therefore we can assume that composites presented in this paper will be a good analogue conventional carbon nanotubes traditionally used in the electronics emission during the creation of a new generation matrix cathodes. Search the equilibrium configuration of composites was carried out by molecular mechanical model with the potential REBO using the software package KVAZAR. Calculation of ionization potential of the composites was performed by tight-binding quantum-chemical method. Calculation of electric field amplification factor for the equilibrium configuration of the composite is carried out by finite element software package ANSYS.
