"Thanks to their extremely high mobilities, semiconducting carbon nanotubes (CNTs) are a promising material for high speed electronics. Beyond that, CNT networks are inherently flexible and stretchable and can be processed from dispersions resulting in devices with still remarkable electronic properties. They can fulfill many of the various requirements for novel applications including fast switching speeds and high currents at low drive voltages. Depending on the intended use, one or another device property might be more important. CNT networks, processes, and architectures can be tailored to yield devices that can serve the respective purpose. Highly purified semiconducting CNTs are, however, still rather expensive and direct-write techniques are thus preferred to enable variable designs and reduce manufacturing costs.\r\nIn this work, aerosol-jet printing is investigated as a deposition technique for CNTs that works with small ink volumes but can also be upscaled by parallelization and integrated into high-throughput roll-to-roll printing processes. After the development of printable inks, it is shown that the printing process itself has no influence on the quality of the CNTs although sonication is used to transfer the ink into an aerosol. The electronic properties of CNT networks incorporated in an established transistor structure exhibit reproducibility comparable to other deposition techniques. Moreover, additive manufacturing enables the deposition of several layers on top of each other to increase the overall film thickness up to optically dense films visible to the naked eye. Field-effect mobilities and on-conductances increase and the hysteresis decreases for thicker films compared to dense but thin networks. \r\nBased on these findings, CNT films are printed with a thickness of 50–600 nm and vertical charge transport is demonstrated. These films are subsequently sandwiched between electrodes and electrolyte-gating results in doping of CNT films throughout electrode overlap areas of several hundred µm2. The vertical device architecture decouples the printing accuracy from the critical device dimensions while supporting high currents for a small footprint. A comparison of different printed electrode materials reveals the superior properties of printed metals over mixed (metallic and semiconducting) CNTs. Electrodes based on inkjet-printed gold nanoparticles are additionally used on flexible substrates and stable device performance even after several hundred bending cycles is demonstrated for vertical and lateral CNT network transistors. These all-printed devices are promising for further development of electronic circuits that do not require high operating frequencies but rather flexibility, high-currents, and small footprints."^^ .
