Abstract:
At the ISSTT2006, we presented experimental results for a new microwave (~ 1GHz) direct and heterodyne detector based on metallic Single-Walled Carbon Nanotubes (m-SWNTs). We now report on microwave detection in several different contact configurations, and the methods used to fabricate these. One such configuration is a log-periodic toothed terahertz antenna with which we have now (soon after the conference) detected terahertz radiation from laser sources up to 1.63 THz. We also report on ab-initio simulations relevant for interpreting the experimental data. We argue that exploring the properties of single m-SWNTs at terahertz should be very fruitful.
