“…While the above plasma wave model was based on the hydrodynamic particle behaviour, the models mentioned here depart from the plasma wave image and use the complete set of hydrodynamic equations to extract the FET response. Many studies have used the hydrodynamic model to derive an analytical equation to describe the electrical properties of teraFET detectors [33][34][35][36][37][38][39], while others used hydrodynamic equations within TCAD (Technology Computer-Aided Design) simulators [40][41][42]. The continuity equation can be described by equation (2Error!…”

“…However, to account for the collisions with phonons and impurities, Aizin [53] presumptively used a ballistic electron transport model. The excess carrier concentration in the channel of TeraFETs that is created by the photoexcitation was studied [34,[54][55][56] by using 2D HDM. In these works, they used a 2D hydrodynamic approach to describe the excess carrier concentration generated by the laser photoexcitation.…”

Despite the advantages of semiconductor field-effect transistors (FETs), they have yet to show competing responses in terahertz (THz) radiation detection compared to other techniques. It is therefore important to improve our understanding of the FET operation when detecting THz radiation beyond its cut-off frequency. The journey of modeling THz detection in FET started with the plasma wave model by Dyaknov and Shur and proceeded to other approaches to develop a physicsbased model of the FET nonlinearity that drives the high-frequency rectification. This work presented a review of the models developed to model the operation of FEET detectors. The common factors as well as the advantages of each model are emphasized. The more we understand these models, the better we can guide the development of FET designs for higher detection responses.
