Generic Compact Model Development of Double-Gate MOSFETs with Inclusion of Different Operation Modes and Channels from Heavily Doped to Intrinsic Case

Zhou X., Zhang J., Zhang L., Zhang J., Zhang L., Ma C., He J., Chan M., Peking University, CN

In this paper, the Double-Gate MOSFET’s operation modes such as symmetric, asymmetric and independent-gate-operation are discussed and an idea for the generic compact model development is proposed. It is shown that the presented generic model [...]

An Analytic Terahertz Signal Detection Model of Silicon-based Nanowire Gated Field Effect Transistor

He F., Chen Y., Mu X., Lou H., Zhang L., Song Y., SZPKU, CN

In this paper, an analytical terahertz (THz) signal detection model of Silicon-based nanowire MOSFET (NWFET) is proposed. Beginning from the fundamental hydrodynamic transport equations, the expressions of the velocity spatial distribution and inversion charge transport [...]

Performance study of Ballistic and Quasi-Ballistic on Double-Gate MOSFETs 6T SRAM cell

Martinie S., Jaud M-A, Munteanu D., Thomas O., Le Carval G., Autran J-L, CEA/LETI/MINATEC, FR

The impact of ballistic/quasi-ballistic carrier transport on the switch of a CMOS inverter and on the noise margin of a 6T SRAM cell, both based on Double-Gate MOSFETs (DGMOS), is analysed using mixed-mode simulation. To [...]

Simulation of Decrease in Lag phenomena and Current Slump of Field-Plate GaAs FETs

Itagaki K., Ueda H., Terao Y., Horio K., Shibaura Institute of Technology, JP

Two-dimensional transient analysis of field-plate GaAs MESFETs is performed in which a deep donor “EL2” and a shallow acceptor are considered in a semi-insulating substrate, and the results are compared between the two cases with [...]

Determination of droplet shape in digital microfluidic systems using two-dimensional flow analysis

Ahmadi A., Najjaran H., Holzman J.F., Hoorfar M., University of British Columbia Okanagan, CA

A two-dimensional model for fluid flow in a digital microfluidic system is introduced, and the results are compared to experimental data. Resistive flow effects based upon contact line forces, filler effects and shear forces are [...]

A Comparison of Surface Acoustic Wave Modeling Methods

Wilson W.C., Atkinson G.M., NASA Langley Research Center, US

Surface Acoustic Wave (SAW) technology is low cost, rugged, lightweight, extremely low power and can be used to develop passive wireless sensors. For these reasons, NASA is investigating the use of SAW technology for Integrated [...]

Sacrificial membranes for serial valving in microsystems

Allain M., Berthier J., Basrour S., Pouteau P., CEA/LETI/MINATEC, FR

Valving is essential to microflow circuits in microsystem technology. Many different types of valves have already been designed. Membranes of sacrificial materials have been studied for one shot valving; however, the new design proposed here, [...]

Kinetic Monte Carlo Study on Carbon Trapping Effect with Pre-amorphized Silicon

Park S., Cho B., Won T., Inha University, KR

We report our kinetic Monte Carlo (kMC) study of the effect of carbon co-implant on the pre-amorphization implant (PAI) process. We employed BCA (Binary Collision Approximation) approach for the acquisition of the initial as-implant dopant [...]

Finite Element Method and Genetic Algorithm for Analysis MEMS

Ortiz V.H., Chairez I., Biochip Bubbles, MX

This paper presents an analysis of the finite element method (FEM) and genetic algorithms for the analysis of MEMS and BIOMEMS design. The finite element method is the method used for the computational analysis of [...]

Determination of Non-local Elasticity Constants for the Torsional Buckling of Single-Wall Carbon Nanotubes Using Molecular Dynamics

Khademolhosseini F., Rajapakse R.K.N.D., Nojeh A., University of British Columbia, CA

Recently, devices have been developed which use Carbon Nanotubes (CNTs) as torsional spring elements. In order to define the range of applicability of CNTs in such devices, it is important to fully understand their torsional [...]
