Outline of Final Research Achievements |
Carbon nanotubes (CNTs) have been attracting much attention due to wide application areas thanks to their excellent electric, mechanical, and thermal properties. We presented a simple model for the drain current of CNT network thin-film transistors (TFTs) operated in the linear region. The model was based on the gate electrostatics and the continuity condition of the currents through CNT and CNT-CNT tunnel junction. The model was evaluated by comparing its calculations to experimentally measured drain current and low frequency (1/f) noise parameters. It provides useful information to improve the TFT performance. We calculated the complex permittivity of materials required to achieve a single-layer electromagnetic absorber with a high absorption coefficient in the 60-GHz band. On the basis of the findings, we developed three types of nonwoven fabrics with high porosity in which the fibers were coated with multiwalled carbon nanotubes.
