Abstract: The exceptional electronic, thermal, mechanical and optical characteristics of carbon nanotubes (CNTs) offer significant performance improvement in a variety of applications. However, precise alignment and control of CNTs are bottlenecks for many applications. Thin films or composites using a large number of nanotubes in random networks, mats or parallel arrays offer a potential solution, as these structures are relatively inexpensive and are compatible with large scale manufacturing. CNT network based thin films have motivated extensive study for their possible use in ] diverse applications of electronic devices, avionic structures, energy conversion devices, thermal interface materials, interconnects, sensors, solar cells and hydrogen storage devices. Carbon nanotube networks based thin-film transistors (CN-TFTs) have been considered as strong candidates to improve mobility, flexibility, transparency in applications such as active matrix display drivers, antennas and sensors. In this talk, an overview of CN-TFTs and its different applications will be presented. How the behavior of nanotube networks in its nano-electronic devices, regardless of the visual complexity, can be understood as a consequence of the mathematical properties of the tube percolation network will be discussed. Finally, power dissipation and network breakdown in CN-TFTs and their percolating networks will be presented.
