Subthreshold Quantum Ballistic Current and Quantum Threshold Voltage Modeling for Nanoscale FinFET

Monga U., Fjeldly T.A., UniK/Norwegian University of Science and Technology, NO

A subthreshold quantum ballistic current model and a quantum threshold voltage model is presented for nanoscale FinFET.The eigenvalues are determined by solving Schrödinger equation along the gate-to-gate axis. The current is then modeled using Natori’s [...]

Analytical Potential Distribution Model for Underlap Double Gate MOSFETs with 3T-4T and Symmetric- Asymmetric Options for Subthreshold operation: A Conformal Mapping Approach

Vaddi R., Dasgupta S., Agarwal R.P., Indian Institute of Technology, Roorkee, IN

We propose a new analytical model to compute the potential distribution in gate overlap and underlap regions of a 3T- 4T double gate MOSFET valid for symmetric, asymmetric options for operation in the subthreshold condition. [...]

Compact Quantum Modeling Framework for Nanoscale Double-Gate MOSFET

Monga U., Fjeldly T.A., Norwegian University of Science and Technology, NO

A quantum mechanical modeling framework for ultra-thin body double-gate MOSFETs operating in subthreshold and near-threshold regime is presented. For subthreshold conditions, we have assumed that the electrostatics is dominated by capacitive coupling between the body [...]

Precise 2D Compact Modeling of Nanoscale DG MOSFETs Based on Conformal Mapping Techniques

Fjeldly T.A., Kolberg S., Norwegian University of Science and Technology, NO

In nanoscale double gate MOSFETs, the dependence on the bias voltages of the 2D electron barrier topology in the conducting channel is all-important for the operation of the device. We consider a DG MOSFET with [...]

Modeling of Electrostatic MEMS Components

Lorenz G., Neul R., Dickmann S., Robert Bosch GmbH, DE

This paper describes an analytical approach for the network-type modeling of pull-in comb drives based on a mathematical field description using conformal mapping methods. The model was coded in MAST R for the SABER R [...]
