Shubnikov De Haas Oscillations

The role of gated and ungated two dimensional (2D) electron plasma in THz detection by high electron mobility transistors (HEMTs) was investigated. THz response of GaAs / AlGaAs and GaN / AlGaN HEMTs was measured at 4.4K in quantizing magnetic fields with a simultaneous modulation of the gate voltage UGS. This allowed us to measure both the detection signal, S, and its derivative d S/ d UGS. Shubnikov - de-Haas oscillations (SdHO) of both S and d S/ d UGS were observed. A comparison of SdHO observed in detection and magnetoresistance measurements allows us to associate unambiguously SdHO in S and d S/ d UGS with the ungated and gated parts of the transistor channel, respectively. This allows us to conclude that the entire channel takes part in the detection process. Additionally, in the case of GaAlAs / GaAs HEMTs, a structure related to the cyclotron resonance transition was observed.
