An Online Mems Design Tool That Lays Out and Simulates a Parameterized Array from a Reference Device

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

We present an online MEMS design tool that lays out and simulates a parameterized array from a reference device. These automated features are implemented in our tool called SugarCube, which is readily available on nanoHUB.org. [...]

A Systems Design Framework Based in Matlab That Integrates Sugar, Spice, Simulink, Fea Comsol, and GDS-II Layout

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

We present a systems design framework called iSUGAR that integrates SUGAR, SPICE, SIMULINK, FEA COMSOL, and GDS-II layout. SUGAR is known for its ease and speed of complex MEMS configuration and parameterization; SPICE is known [...]

Neuromorphic Logic Networks and Robust Stochastic Computing Under Large Perturbations and Uncertanties

Lyshevski S.E., Rochester Institute of Technology, US

This paper contributes to robust fault-tolerant neuromorphic computing for expected nano-centric processing hardware. We develop: (a) A library of neuromorphic networks for elementary logic function in order to enable the design of an arbitrary complexity [...]

The role of Electromechanical coupling in AlGaN/AlN/GaN HEMTs

Padmanabhan B., Vasileska D., Goodnick S.M., Arizona State University, US

we present simulation results for GaN HEMTs in which the structure has additional AlN spacer layer thus completely modifying the electromechanical coupling approach.

High-Fidelity Modeling of Single Molecule Quantum Electronic Devices

Lyshevski S.E., Rochester Institute of Technology, US

Departing from two-terminal molecular electronic devices, this paper examines multi-terminal MEdevices. These devices are envisioned to be utilized in emerging molecular gates (Mgates) and neuronal hypercells for expected molecular integrated circuits. High-fidelity modeling and heterogeneous [...]

Simplifying the Designing of a MEMS-based Nanoscale Material Testing Device

Bansal R., Clark J.V., Purdue University, US

Microelectromechanical-systems (MEMS) are increasingly used for accurate mechanical characterization of nanostructures. However, the performance of such systems highly depends on their structural design. Optimizing the performance of the device using distributed analysis is computationally expensive, [...]

Lumped Modeling of Carbon Nanotubes for M/NEMS Simulation

Bansal R., Clark J.V., Purdue University, US

The construction and analysis of the CNT structure is extremely difficult and requires expertise in nanostructure physics. This limits access to molecular dynamics specialists and does not allow the exploration of CNTs as components of [...]

Carbon Nanotube Field Effect Transistor (CNTFET) 2-D Channel Electrostatic Potential Model for TCAD Application

Abebe H., Cumberbatch E., USC, US

A 2-D channel electrostatic potential model of CNTFET is presented. The model is developed by directly solving Laplace’s equation in cylindrical coordinates with appropriate boundary conditions. To the best of our knowledge, the Technology Computer [...]

SUGARX: A Online Tool That Bridges the Gap Between Experiment and Simulation

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

We present a pioneering online tool called SugarX that, for the first time, bridges the gap between experiment and simulation. Our tool is available online at nanoHUB.org with remote experimental control and simulation. A web [...]

CFD-Assisted Design and Optimization of a Pharmacokinetic Microfluidic System

Moeini Sedeh M., Khodadadi J.M., Hong J.W., Cramer K.A., Hamon M., Auburn University, US

In this research, a microfluidic system was designed and optimized to carry out in vitro pharmacokinetic studies of drug candidates in the liver. Computational fluid dynamics (CFD) was called on to assist in the system [...]
