Polymer-Based Memristive Devices for Ammonium Biosensing

Memristive devices offer a promising approach for biosensing due to their high sensitivity. In two-terminal planar devices, the movement of charged species in the semiconductor channel creates a voltage gap, which can be exploited for sensing. In this stud ...

Analytical analysis of Quasi-Saturation Effect in PT and NPT IGBTs

Alfred Rufer, Serge Pittet

During the turn-on process insulated gate bipolar transistors (IGBTs) traverse a quasi-saturation region from the off.state to the on-state (saturation). The additional voltage drop due to the quasi.saturation of the junction hardly depends on the DC-link ...
