The fabricated&nbsp; circuits function in <em>Ku<\/em>-band&nbsp; between&nbsp; 12&nbsp; and&nbsp; 18GHz, and are the best-performing&nbsp; power&nbsp; detectors&nbsp; fabricated&nbsp; on&nbsp; flexible&nbsp; substrate&nbsp; reported&nbsp; to&nbsp; date. Their dynamic range exceeds 30dB, outperforming&nbsp;&nbsp; other semiconductor&nbsp;&nbsp; technologies, like silicon complementary metal oxide semiconductor (CMOS) circuits and GaAs Schottky diodes.<\/p>\n\n\n\n<!--more-->\n\n\n\n<p>Power detectors are important building blocks of analog wireless-applications, such as radar systems, Radio Frequency Identification (RFID) transceivers, and mobile communications. Their functioning relies on the non-linear operation of a single field-effect transistor (FET). The newly published work reports the successful implementation of zero-bias RF power detectors based on two different MoS<sub>2<\/sub> FETs with mono-and multilayer channel materials, both fabricated with a growth and fabrication technique suitable for large-scale manufacturing.<\/p>\n\n\n\n<p>The results clearly indicate the potential of MoS<sub>2<\/sub> FETs for realizing fully integrated, flexible, low-power transceivers. At the same time, the work also shows that some material-growth and device-processing parameters still need to be carefully tuned in order&nbsp; to&nbsp; allow&nbsp; these&nbsp; circuits to&nbsp; meet&nbsp; the rigorous reliability&nbsp; requirements&nbsp; of mass&nbsp; production.<\/p>\n\n\n\n<p>The work has been published open-access on <a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/adma.202108469\">Advanced Materials<\/a>.<\/p>\n\n\n\n<p>Bibliographic information<br><strong>Zero Bias Power Detector Circuits based on MoS2 Field Effect Transistors on Wafer-Scale Flexible Substrates<\/strong><br>E.
