Semi-quantitative estimation of the characteristic detection length combined with self-consistent calculations of the electric fields excited in the structure by incoming terahertz radiation allowed us to interpret quantitatively the results and conclude that this detection takes place mainly in the regions of strong oscillating electric field excited in depleted portions of the channel. %G English %L hal-00545630 %U https://hal.science/hal-00545630 %~ CNRS %~ UNIV-MONTP2 %~ GES %~ UNIV-MONTPELLIER %~ UM1-UM2
