Plasma wave detection of sub-terahertz and terahertz radiation by silicon field-effect transistors

Abstract: We report on experiments on photoresponse to sub-THz ͑120 GHz͒ radiation of Si field-effect transistors (FETs) with nanometer and submicron gate lengths at 300 K. The observed photoresponse is in agreement with predictions of the Dyakonov-Shur plasma wave detection theory. This is experimental evidence of the plasma wave detection by silicon FETs. The plasma wave parameters deduced from the experiments allow us to predict the nonresonant and resonant detection in THz range by nanometer size silicon devices-ope… Show more

“…They have large refractive indices leading to high surface reflection loss at the interface between the substrate and air. [14][15][16] In previous work, the quarter-wavelength-thick ARC showed enhanced transmission at resonance wavelengths on perforated gold film in the infrared regime. 17 However, the wavelength range in which the transmission is enhanced was around 2 µm due to the narrowband antireflection characteristics.…”

“…[1] Последнее двадца-тилетие ознаменовалось успехами в создании детекторов на основе полевых транзисторов, способных принимать сигнал в ТГц диапазоне [2][3][4][5][6][7][8][9]. Первый такой детектор был создан на базе транзистора с высокой подвижностью электронов (high electron mobility transistor, HEMT) и принимал сигнал на частоте 2.5 THz [2].…”

“…Вслед за ис-следованиями транзисторов на основе соединений III и V групп (GaAs/AlGaAs, GaInAs/AlGaAs, GaN/GaAlGaN и др.) [2][3][4][5] была продемонстрирована возможность де-тектирования на кремниевом транзисторе [6,7]. Хорошо развитая кремниевая технология позволяет интегриро-вать большое число транзисторов на единой пластине, делая возможным создание матричных приемников [8,9].…”
