Improving terahertz-detection sensitivity of 8x8 FET arrays through liquid-nitrogen cooling in a compact low-noise cryostat
Jakob Holstein, Nicholas K. North, Arne Hof +10
We show that the sensitivity of antenna-coupled field-effect transistors (FETs) to terahertz (THz) radiation improves continuously with decreasing temperature. The noise-equivalent…

Modeling of antenna-coupled Si MOSFETs in the Terahertz Frequency Range
Florian Ludwig, Jakob Holstein, Anastasiya Krysl +2
We report on the modeling and experimental characterization of Si CMOS detectors of terahertz radiation based on antenna-coupled field-effect transistors (TeraFETs). The detectors…
