|Terahertz Detection by InGaAs HEMTs in Quantizing Magnetic Fields: relation between magnetoresistance and photovoltaic response |
Conference: 35th International Conference on Infrared, Millimeter and Terahertz Waves (, IT, 2010-09-05)
THz detection by plasma wave mechanism in InGaAs HEMTs is studied in high/quantizing magnetic fields regime. The correlation between the photovoltaic response and magnetoresistance is revealed. It allows to explain the nature of strong oscillations observed in the transistor Terahertz photoresponse.
