Sensing device for sensing minor charge variations

Mihai Adrian Ionescu, Teodor Rosca, Cem Alper

A charge sensing device for sensing charge variations in a charge storage area includes: a TFET having at least one sense gate; and a capacitive coupling for coupling the charge storage area with the sense gate. ...

Modeling and optimization of Tunnel-FET architectures exploiting carrier gas dimensionality

Cem Alper

The semiconductor industry, governed by the Moore's law, has achieved the almost unbelievable feat of exponentially increasing performance while lowering the costs for years. The main enabler for this achievement has been the scaling of the CMOS transistor ...

A Steep-Slope Transistor Combining Phase-Change and Band-to-Band-Tunneling to Achieve a sub-Unity Body Factor

Mihai Adrian Ionescu, Anna Krammer, Teodor Rosca, Josef Andreas Schuler, Cem Alper, Wolfgang Amadeus Vitale, Arnab Biswas, Emanuele Andrea Casu, Qun Zhao

Steep-slope transistors allow to scale down the supply voltage and the energy per computed bit of information as compared to conventional field-effect transistors (FETs), due to their sub-60 mV/decade subthreshold swing at room temperature. Currently pursu ...

Benchmarking of Homojunction Strained-Si NW Tunnel FETs for Basic Analog Functions

Mihai Adrian Ionescu, Cem Alper, Arnab Biswas, Florin Udrea

This paper reports a compact ambipolar model for homojunction strained-silicon (sSi) nanowire (NW) tunnel FETs (TFETs) capable of accurately describing both I-V and G-V characteristics in all regimes of operation, n- and p-ambipolarity, the superlinear ons ...

Band-to-band tunneling distance analysis in the heterogate electron-hole bilayer tunnel field-effect transistor

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

In this work, we analyze the behavior of the band-to-band tunneling distance between electron and hole subbands resulting from field-induced quantum confinement in the heterogate electron-hole bilayer tunnel field-effect transistor. We show that, analogous ...

Hybrid phase-change — Tunnel FET (PC-TFET) switch with subthreshold swing < 10mV/decade and sub-0.1 body factor: Digital and analog benchmarking

Mihai Adrian Ionescu, Anna Krammer, Teodor Rosca, Josef Andreas Schuler, Wolfgang Amadeus Vitale, Cem Alper, Arnab Biswas, Emanuele Andrea Casu, Nicolò Oliva

In this paper we report the first hybrid Phase-Change - Tunnel FET (PC-TFET) device configurations for achieving a deep sub-thermionic steep subthreshold swing at room temperature and subthreshold power savings. The proposed hybrid device feedbacks the ste ...

Assessment of Confinement-Induced Band-to-Band Tunneling Leakage in the FinEHBTFET

Mihai Adrian Ionescu, Cem Alper, José Luis Padilla de la Torre

In conventional planar EHBTFETs, the interband tunneling phenomena responsible for the drive current takes place vertically in the section of the channel where top and bottom gates overlap. As a result, the horizontal extent of this overlapping between gat ...
