The detector was operated with both a table-top system until 1.2 THz and at a Free-Electron Laser (FEL) facility at singular frequencies from 1.9 to 5.56 THz. We used two measurement techniques in order to discriminate the sub-ns-scale (via a 20 GHz oscilloscope) and the ms-scale (using the lock-in technique) responsivity. While the lock-in measurements basically contain all rectification effects, the sub-ns-scale detection with the oscilloscope is not sensitive to slow bolometric effects caused by changes of the IV characteristic due to temperature. The noise equivalent power (NEP) is 10 pW\/Hz in the frequency range from 0.2 to 0.6 THz and 17 pW\/Hz at 1.2 THz and increases to 0.9 \u03bcW\/Hz at 5.56 THz, which is at the state of the art for room temperature zero-bias Schottky diode-based THz detectors with non-resonant antennas. The voltage and current responsivity of \u223c500 kV\/W and \u223c100 mA\/W, respectively, is demonstrated over a frequency range of 0.2 to 1.2 THz with the table-top system.<\/jats:p>","DOI":"10.3390\/s23073469","type":"journal-article","created":{"date-parts":[[2023,3,27]],"date-time":"2023-03-27T03:01:14Z","timestamp":1679886074000},"page":"3469","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["State-of-the-Art Room Temperature Operable Zero-Bias Schottky Diode-Based Terahertz Detector Up to 5.56 THz"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7204-4833","authenticated-orcid":false,"given":"Rahul","family":"Yadav","sequence":"first","affiliation":[{"name":"High Frequency Technology, Mittelhessen University of Applied Sciences, 61169 Friedberg, Germany"},{"name":"Terahertz Devices and Systems, TU Darmstadt, 64283 Darmstadt, Germany"}]},{"given":"Florian","family":"Ludwig","sequence":"additional","affiliation":[{"name":"Institute of Physics, Johann Wolfgang Goethe University, 60438 Frankfurt am Main, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8076-0840","authenticated-orcid":false,"given":"Fahd Rushd","family":"Faridi","sequence":"additional","affiliation":[{"name":"Terahertz Devices and Systems, TU Darmstadt, 64283 Darmstadt, Germany"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3431-6666","authenticated-orcid":false,"given":"J.
