Those who write compact models for use in circuit simulation need a basic understanding of what goes on inside a circuit simulator. This presentation is a short introduction for beginners. It briefly covers how circuit equations (so-called Differential Algebraic Equations, DAEs) are built up and how they are solved to find the circuits’ steady state solutions (by Newton Raphson iteration). It also discusses how circuits are defined (in netlist format), how different kinds of analyses (DC, AC, …

Graphene nanoribbons (often abbreviated as GNR) are planar strips of graphene with a thickness of approximately one atom. Carbon atoms in graphene are sp2-hybridized with a carbon-carbon bond length of approximately 0.142 nm. As an electronic material, graphene exhibits many desirable properties, such as high carrier mobility, a thin body and compatibility with top down fabrication. A graphene nanoribbon can be either a zig-zag or arm-chair type. Both zig-zag and armchair type GNR are shown …

In the 20th century transistor performance improvement was driven by dimensional scaling; dimensional scaling in turn was driven by scaling of the wavelength of light used for patterning. However, in the last decade, new and innovative techniques have been used to drive transistor performance and dimensional scaling forward. This talk will focus on some of the techniques that have been used to enable Moore’s law over the last decade as well as the prognosis for future scaling.

The nanoMATERIALS simulation tool https://nanohub.org/resources/matsimtk enables running live MD simulations in nanoHUB.org. A simple-to-use graphical interface allows users to set up the initial structure, simulation conditions (e.g. thermodynamic ensemble, temperature, strain rate), and output options; advanced options enable users to compute thermal conductivity using non-equilibrium simulations. Learn more about the nanoMATERIALS simulation tool and run simulations via the following tutorials: Running MD on the nanoHUB: The nano-MATERIALS Simulation Toolkit. http://nanohub.org/resources/5843 Materials strength: does size matter? nanoMATERIALS simulation toolkit tutorial. https://nanohub.org/resources/2322 MD in research and education First Principles-based Atomistic and Mesoscale Modeling of Materials. https://nanohub.org/resources/434 Learning Module: Atomic picture of plastic deformation in metals.

Bogdan Vladislavovich Natalich onto MD

This set of ten presentations accompanied a graduate level course on Molecular Dynamics simulation. The specific objective of the course (and the presentations) is to provide: 1. Awareness of the opportunities and limitations of Molecular Dynamics as a tool for scientific and engineering research 2. Understanding of the compromise between model complexity/realism and computational expense 3. Background that enables interpretation of Molecular Dynamics-based studies reported in the literature

Molecular dynamics simulations are playing an increasingly important role in many areas of science and engineering, from biology and pharmacy to nanoelectronics and structural materials. Recent breakthroughs in methodologies and in first principles-based interatomic potentials significantly increased the range of applicability of MD and the accuracy of its predictions even for new materials not yet fabricated or synthesized. Such predictive power indicates that MD has the potential to play a key role in guiding the design and optimization of new materials with improved properties tailored for specific applications.

The goal of this short course is to provide an introduction to the theory behind MD simulations, describe some of the most exciting recent developments in the field and exemplify its use in various applications. The short course consists of a brief introduction and three lectures.

One of the most powerful tools on nanoHUB is something we call a workspace, which is a full-featured Linux desktop that you can access any time, any place, from your web browser. Workspaces are fully loaded with the latest nanoHUB software stack, including the Rappture toolkit, Octave, Scilab, a variety of compilers, and other handy utilities. This tutorial shows how to use workspaces for research and for tool development. It shows how to request access to workspaces, how to launch them, how …
