| Abstract(in English) | Understanding physical mechanisms of photonic response in microwave devices such as MODEFT's is important in implementing high speed radio-on-fiber systems. We considered the gate current path as two Schottky diodes connected back-to-back where the gate metal plate and the barrier semiconductor layer constitutes the first Schottky diode and the barrier semiconductor layer and the two-dimensional electron (hole) gas formed in the channel constitutes the second Schottky diode. An analytic expression for the gate current in terms of the barrier heights of the two Schottky diodes is derived. When the photonic illumination generates the photocarries in the channel, the barrier heights are modified via the change in the Fermi level. This also explains the shift of the threshold voltage with the photonic illumination. The result shows rather linear relation between the gate current and the photonic illumination intensity under certain conditions. |
