Non Quasi-Static Model of DG Junctionless FETs

Jean-Michel Sallese, Farzan Jazaeri

In this paper an analytical non-quasi-static (NQS) model for long-channel symmetric double-gate junctionless field-effect transistors (JLFETs) operating in depletion mode is proposed for the first time. The model addresses the limitations of existing DC an ...

Design space of quantum dot spin qubits

Jean-Michel Sallese, Farzan Jazaeri, Amin Rassekh

Solid-state qubits can be implemented with electrostatically confined quantum dots in semiconductors, allowing gate voltages to independently control the electrochemical potentials of each quantum dot. Quantum dots offer high levels of reliability and scal ...

Transcapacitances Modeling in ultra-thin gate-all-around junctionless nanowire FETs, including 2D quantum confinement

Farzan Jazaeri

In this work, we propose an analytical model for the intrinsic transcapacitances in ultra-thin gate-all-around junctionless nanowire field effect transistors in the presence of confined energy states of electrons. The validity of the developed model is con ...

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) ...

Accounting for Optical Generation in the Quasi-Neutral Regions of Perovskite Solar Cells

Jean-Michel Sallese, Farzan Jazaeri, Parnian Ferdowsi, Michael Saliba

Predicting the performance of solar cells though analytical models is important for the theory-guided optimization of these devices. Earlier models neglect the impact of the optical generation in the quasi-neutral regions of a perovskite solar cell. Here, ...
