摘要：

We present new data on microwave detection in bundles of carbon nanotubes (CNTs). In particular, we derive a circuit model based on ANA measurements. We also demonstrate the first terahertz detection (up to 2.54 THz) in bundles of CNTs that were deposited through dielectrophoresis across the smallest gap in log-periodic antennas. Data are given that support the hypothesis that the detection process is bolometric at THz frequencies. Future extensions are planned that will employ suspended CNTs and explore heterodyne detection. Finally, we have performed unique ab initio simulations of CNTs with the aim of comparing these with the experimental data.
