“…The main difference is that GR films are planar, whereas CNT electrodes have a large length/ diameter ratio. As a result, the electric field at the tip of CNTs can be a hundred times higher than that of planar structures, which is expected to improve charge injection by assisting the tunneling process from CNTs into OSCs [154]. This mechanism occurs regardless of carrier type and should promote tunneling of both electrons and holes.…”

“…Because Valitova et al [154] provided a decent review on the recent application of carbon nanotubes (CNTs) in OFETs, here we only briefly compare CNTs and GR as electrodes for OFETs. Similar to GR electrodes, CNTs have a medium work function ($4.8 eV) and thus CNT arrays are suitable for both hole and electron injection [155,156].…”

Organic field-effect transistors (OFETs) are promising for numerous potential applications but suffer from poor charge injection, such that their performance is severely limited. Recent efforts in lowering contact resistance have led to significantly improved field-effect mobility of OFETs, up to 100 times higher, as the results of careful choice of contact materials and/or chemical treatment of contact electrodes. Here we review the innovative developments of contact engineering and focus on the mechanisms behind them. Further improvement toward Ohmic contact can be expected along with the rapid advance in material research, which will also benefit other organic and electronic devices.

“…Carbon nanotubes (CNTs) have been shown to be promising materials for various applications, such as biological and biomedical research [ 160 , 161 ], environmental science [ 162 ], catalysis [ 163 ], fabrication of composite materials [ 164 ], microelectronics [ 165 ], solar cells [ 166 , 167 ], electronic components [ 168 , 169 ], energy storage [ 170 ], hydrogen storage [ 171 ], and so on. The PBI-based composed membranes with CNTs (PBI/CNT) were investigated and their properties were compared with the plain PBI membrane.…”

The rapid increasing of the population in combination with the emergence of new energy-consuming technologies has risen worldwide total energy consumption towards unprecedent values. Furthermore, fossil fuel reserves are running out very quickly and the polluting greenhouse gases emitted during their utilization need to be reduced. In this scenario, a few alternative energy sources have been proposed and, among these, proton exchange membrane (PEM) fuel cells are promising. Recently, polybenzimidazole-based polymers, featuring high chemical and thermal stability, in combination with fillers that can regulate the proton mobility, have attracted tremendous attention for their roles as PEMs in fuel cells. Recent advances in composite membranes based on polybenzimidazole (PBI) for high temperature PEM fuel cell applications are summarized and highlighted in this review. In addition, the challenges, future trends, and prospects of composite membranes based on PBI for solid electrolytes are also discussed.

“…The works [5,6] present high frequency CMOS oscillators integrating CNT or GNR interconnects, whereas [7] shows the first example of a computer with PMOS transistors entirely made of CNTs. Carbon nanotubes or graphene interconnects are also successfully integrated into innovative organic transistors for flexible plastic electronics [8].…”

A semi-classical electrodynamical model is derived to describe the electrical transport along graphene, based on the modified Boltzmann transport equation. The model is derived in the typical operating conditions predicted for future integrated circuits nano-interconnects, i.e., a low bias condition and an operating frequency up to 1 THz. A generalized non-local dispersive Ohm's law is derived, which can be regarded as the constitutive equation for the material. The behavior of the electrical conductivity is studied with reference to a 2D case (the infinite graphene layer) and a 1D case (the graphene nanoribbons). The modulation effects of the nanoribbons' size and chirality are highlighted, as well as the spatial dispersion introduced in the 2D case by the dyadic nature of the conductivity.
