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. [...]

Simulation of Surface and Buffer Trapping Effects on Gate Lag in AlGaN/GaN HEMTs

Horio K., Nakajima A., Fujii K., Shibaura Institute of Technology, JP

Two-dimensional simulation of turn-on characteristics of AlGaN/GaN HEMTs is performed in which both buffer traps and sur-face states are considered. It is studied how the so-called gate lag is affected by these factors. It is [...]

SugarCube: An Online Tool for Investigating the Performance of Ready-Made Parameterized MEMS

Marepalli P., Clark J.V., Purdue University, US

We present an online tool - SugarCube which facilitates the parameterization of ready-made MEMS. Using this tool one can investigate the performance of parameterized MEMS which are available in the form of hierarchical libraries. This [...]

Analysis and Simulation of Curved Bimorph Microactuators

Pal S., Xie H., University of Florida, US

Difference in strains in the two layers of a bimorph causes it to curl, thereby leading to actuation. Thermal, piezoelectric and shape-memory alloy based straight bimorph actuators have been widely reported. However, little attention has [...]

Design and Fabrication of a Low Power Electro-thermal V-shape Actuator With Large Displacement

Khazaai J., Oakland University, US

We propose the design and microfabrication of a V-shape MEMS electro-thermal actuator featuring large displacement generation and low power consumption. Electro-thermal MEMS actuators are suitable for a variety of applications where large forces and long [...]

Design Simulations of MEMS Micropump by 3D Fluid-Structure Interaction Analysis

Johari J., Universiti Kebangsaan Malaysia, MY

The major technical impediment in developing new microdevices lies in the lack of understanding physical phenomena and their interactions of thermal, mechanical, electric, magnetic and/or fluidic fields for performing their intended functions. Due to the [...]

A visual approach on MEMS process modeling using device cross-sections

Schmidt T., Mielke M., Hahn K., Ortloff D., Popp J., Brueck R., University of Siegen, DE

With MEMS entering fast moving consumer markets the need for more efficient design concepts becomes apparent. A technology centered approach where a product is designed around a highly specialized and optimized technology cannot cope with [...]

Development of Device-Level Chemical-Mechanical Polishing Simulation Module Using Cellular Automata Method

Yeh H.-M., Chen K.-S., National Cheng Kung University, TW

This work briefly presents the basic theory, the development, and a primary demonstration of a device-level chemical-Mechanical Polishing (CMP) CAD module. By integrating the phenomenological material removing relation such as Preston’s equation, contact mechanics, finite [...]

3D Molecular Theory of Solvation for Nanochemistry in Solution

Kovalenko A., National Institute for Nanotechnology, CA

Predictive molecular modeling of nanosystems in solution, important in many applications, requires long-time description of millions molecules, which is by far not feasible with ab initio methods, challenging for molecular simulations, and problematic for continuum [...]

Designing nanomaterials mechanical properties from the observable nanostructure features

Tengen T.B., Vaal University of Technology, ZA

Recent findings report that both mean grain size and dispersion should be used to design nanomaterials with desired mechanical properties. Grain size deals with “equivalent radius” that assumes that grains are spherical. But two grains [...]
