Title Terahertz detection in single wall carbon nanotubes Type Journal Article
Year 2008 Publication Applied Physics Letters Abbreviated Journal Appl. Phys. Lett.
Volume 92 Issue 3 Pages 033105
Keywords HEB, single wall, carbon nanotube, CNT, SWNT, SWCNT, terahertz detection, THz
Abstract It is reported that terahertz radiation from 0.69 to 2.54 THz has been sensitively detected in a device consisting of bundles of carbon nanotubes containing single wall metallic carbon nanotubes, quasioptically coupled through a lithographically fabricated antenna, and a silicon lens. The measured data are consistent with a bolometric detection process in the metallic tubes and the devices show promise for operation well above 4.2 K.

Title Terahertz superconducting hot electron bolometer heterodyne receivers Type Journal Article
Year 2007 Publication IEEE Trans. Appl. Supercond. Abbreviated Journal
Volume 17 Issue 2 Pages 252-258
Keywords HEB, mixer, direct detection effect
Abstract We highlight the progress on NbN hot electron bolometer (HEB) mixers achieved through fruitful collaboration between SRON Netherlands Institute for Space Research and Delft University of Technology, the Netherlands. This includes the best receiver noise temperatures of 700 K at 1.63 THz using a twin-slot antenna mixer and 1050 K at 2.84 THz using a spiral antenna coupled HEB mixer. The mixers are based on thin NbN films on Si and fabricated with a new contact-process and-structure. By reducing their areas HEB mixers have shown an LO power requirement as low as 30 nW. Those small HEB mixers have demonstrated equivalent sensitivity as those with large areas provided the direct detection effect due to broadband radiation is removed. To manifest that a HEB based heterodyne receiver can in practice be used at arbitrary frequencies above 2 THz, we demonstrate a 2.8 THz receiver using a THz quantum cascade laser (QCL) as local oscillator.
