An Efficient Iterative Grid Selection Strategy for Time-Mapped Harmonic Balance Method

Xu Z., Peking University, CN

In this paper, a new iterative grid selection strategy for the Time-Mapped Harmonic Balance (TMHB) method is presented. This strategy is referred to the adaptive grid methods, which tracks the rapid transitions and constructs a [...]

Nonparabolicity Effects of the Ultra-thin Body Double-gate MOSFETs

Lou H., Peking University, CN

In this paper, the band-structure of ultra-thin body (UTB) double-gate (DG) MOSFETs is calculated by empirical tight-binding model, and the the nonparabolicity effects are included in the model by the modified Schrödinger equation with the [...]

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, [...]

Modeling a plane 3 DOF compliant micromanipulator

Verotti M., University of Rome “La Sapienza”, IT

In the present work, a new MBS (Multi-Body System) code has been dedicated to the static and dynamic analysis of micro-compliant mechanisms. Although the inertial force become more and more negligible, the smaller becomes the [...]

Numerical evaluation of growth conditions of GaN-based LEDs in multiwafer MOCVD reactor

Yang L., Zhang J., Hu J., Shanghai University, CN

In this paper, numerical evaluation of growth conditions of GaN in multiwafer planetary MOCVD reactor was carried out. The growth of GaN films using TMGa as a precursor, hydrogen and nitrogen as carrier gas was [...]

Application of a Nanoclay-Polypropylene Composite to Efficient Vehicle Occupant Safety Countermeasure Design

Deb A., Venkatesh G.S., Karmarkar A.G., Gurumoorthy B., Indian Institute of Science, IN

Polypropylene (PP) which is a thermoplastic polymer is extensively used in various shades and textures for designing interior trim of vehicles for covering metallic body bestowing an aesthetic and pleasing look as well as providing [...]

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 [...]

Calculated Production Yields in Metallofullerene Series

Slanina Z., Akasaka T., Nagase S., Institute for Molecular Science, JP

The paper reports computations for all lanthanoids L on their encapsulation into the only C74 IPR (isolated pentagon rule) cage (L@C74), for Z@C82 based on encapsulation into the IPR C2v C82 cage, and also for [...]

Dissipative Intrinsic Localized Modes in Nano-ferroelectrics

Biswas A., Chowdhury K., Bandyopadhyay A.K., Bhattacharjee A.K., Mandal D., Dumkal Institute of Engg. & Technology, IN

Ferroelectrics are important materials for optical communication and other important areas of applications where discreteness and nonlinearity causes the formation of intrinsic localized modes that can transport energy with the help of the lattice. Based [...]
