“…CNTs films obtained by the two-step method were studied by us earlier and their structural, topographic and morphological properties were described in other papers [18,19]. In this paper we also correlated the emissive properties of these films with their properties, such as topography and morphology, which were examined by scanning electron microscopy (SEM), and structural properties studied by transmission electron microscopy (TEM).…”

In this paper various types of films made of carbon nanotubes (CNTs) are presented. These films were prepared on different substrates (Al 2 O 3 , Si n-type) by the two-step method. The two-step method consists of physical vapor deposition step, followed by chemical vapor deposition step (PVD/CVD). Parameters of PVD process were the same for all initial films, while the duration times of the second step -the CVD process, were different (15, 30 min.). Prepared films were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and field emission (FE) measurements. The I-E and F-N characteristics of electron emission were discussed in terms of various forms of CNT films. The value of threshold electric field ranged from few V/µm (for CNT dispersed rarely on the surface of the film deposited on Si) up to ∼20 V/µm (for Al 2 O 3 substrate).
