The quasi-continuous exhaust regime in JET

The quasi-continuous exhaust (QCE) regime is a regime that is naturally type-I ELM-free. It combines the high density at the plasma edge needed for power exhaust with the high normalised energy confinement typical for H-mode operation. In the QCE regime la ...

An improved subthreshold swing expression accounting for back-gate bias in FDSOI FETs

Christian Enz, Farzan Jazaeri, Hung-Chi Han

In a MOSFET transistor, the subthreshold swing defines the switching efficiency, and the associated slope factor, or so-called body factor, is a critical parameter in charge-based models. However, in an advanced Fully -Depleted Silicon-On-Insulator (FDSOI) ...
