The author has found that it is the strongly localized terahertz field induced in a small fraction of the gated electron channel that plays an important role in the high responsivity. An AlGaN\/GaN-based high-electron-mobility transistor with a 2-micron-sized gate and integrated dipole antennas has been developed and can offer a noise-equivalent power as low as 40 pW\/Hz1\/2 at 900 GHz. By further reducing the gate length down to 0.2 micron, a noise-equivalent power of 6 pW\/Hz1\/2 has been achieved. This thesis provides detailed experimental techniques and device simulation for revealing the self-mixing mechanism including a scanning probe technique for evaluating the effectiveness of terahertz antennas. As such, the thesis could be served as a valuable introduction towards further development of high-sensitivity field-effect terahertz detectors for practical applications.\u003c\/p\u003e","brand":"Springer","offers":[{"title":"Paperback","offer_id":45277413671063,"sku":"9783662569481","price":3639.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0666\/3471\/1191\/files\/9783662569481.webp?v=1769288300","url":"https:\/\/atlanticbooks.com\/products\/field-effect-self-mixing-terahertz-detectors-9783662569481","provider":"Atlantic Books","version":"1.0","type":"link"}
