  3. On the Reliability of Micro-Electronic Devices: An Introductory Lecture on Negative Bias Temperature Instability

    28 Sep 2005 | Online Presentations | Contributor(s): Muhammad A. Alam

    In 1930s Bell Labs scientists chose to focus on Siand Ge, rather than better known semiconductors like Ag2S and Cu2S, mostly because of their reliable performance. Their choice was rewarded with the invention of bipolar transistors several years later. In 1960s, scientists at Fairchild worked...

  4. Plasmonic Nanophotonics: Coupling Light to Nanostructure via Plasmons

    03 Oct 2005 | Online Presentations | Contributor(s): Vladimir M. Shalaev

    The photon is the ultimate unit of information because it packages data in a signal of zero mass and has unmatched speed. The power of light is driving the photonicrevolution, and information technologies, which were formerly entirely electronic, are increasingly enlisting light to communicate...

  5. Designing Nanocomposite Thermoelectric Materials

    08 Nov 2005 | Online Presentations | Contributor(s): Timothy D. Sands

    This tutorial reviews recent strategies for designing high-ZT nanostructured materials, including superlattices, embedded quantum dots, and nanowire composites. The tutorial highlights the challenges inherent to coupled electronic and thermal transport properties.

  6. Nanoparticle Synthesis and Assembly for Biological Sensing

    25 Oct 2005 | Online Presentations | Contributor(s): Gil Lee

    Nanoparticles have unique physical and chemical properties that make them very useful for biological and chemical sensing. For example, colloidal gold has been used as an optical transducer for antibody based sensing for over twenty years and is the basis for a many of the point-of-use...

  7. Simple Theory of the Ballistic MOSFET

    11 Oct 2005 | Online Presentations | Contributor(s): Mark Lundstrom

    Silicon nanoelectronics has become silicon nanoelectronics, but we still analyze, design, and think about MOSFETs in more or less in the same way that we did 30 years ago. In this talk, I will describe a simple analysis of the ballistic MOSFET. No MOSFET is truly ballistic, but approaching this...

  8. Nano-Scale Device Simulations Using PROPHET

    20 Jan 2006 | Online Presentations | Contributor(s): Yang Liu, Robert Dutton

    These two lectures are aimed to give a practical guide to the use of ageneral device simulator (PROPHET) available on nanoHUB. PROPHETis a partial differential equation (PDE) solver that offers usersthe flexibility of integrating new models and equations for theirnano-device simulations. The...

  9. Nano-Scale Device Simulations Using PROPHET-Part I: Basics

    20 Jan 2006 | Online Presentations | Contributor(s): Yang Liu, Robert Dutton

    Part I covers the basics of PROPHET,including the set-up of simulation structures and parameters based onpre-defined PDE systems.

  13. An Overview of Virtualization Techniques

    03 Feb 2006 | Online Presentations | Contributor(s): Renato Figueiredo

    This presentation presents an introduction to resource virtualizationtechniques, which are one of the foundations of the infrastructure foronline simulation provided by the nanoHUB.

  14. Engineering Nanomedical Systems

    06 Mar 2006 | Online Presentations | Contributor(s): James Leary

    This tutorial discusses general problems and approaches to the design of engineered nanomedical systems. One example given is the engineering design of programmable multilayered nanoparticles (PMNP) to control a multi-sequence process of targeting to rare cells in-vivo, re-targeting to...

  15. A Primer on Scanning Tunneling Microscopy (STM)

    04 Apr 2006 | Online Presentations | Contributor(s): Ron Reifenberger

    Scanning Probe Microscopes and their remarkable ability to provide three-dimensional maps of surfaces at the nanometer length scale have arguably been the most important tool in establishing the world-wide emergence of Nanotechnology. In this talk, the fundamental ideas behind the first scanning...

  16. Understanding Phonon Dynamics via 1D Atomic Chains

    04 Apr 2006 | Online Presentations | Contributor(s): Timothy S Fisher

    Phonons are the principal carriers of thermal energy in semiconductors and insulators, and they serve a vital role in dissipating heat produced by scattered electrons in semiconductor devices. Despite the importance of phonons, rigorous understanding and inclusion of phonon dynamics in...

  17. MATLAB DOs and DON'Ts

    14 May 2006 | Online Presentations | Contributor(s): Dmitri Nikonov

    Matlab is widely used for simulations but is believed to be unsuitable for complex projects and to produce slow-running software tools. The presentation argues that blind copying of methods typical of C and Fortran is responsible for such inefficiencies; the presentation teaches avoidance of...

  18. Nanotubes and Nanowires: One-dimensional Materials

    17 Jul 2006 | Online Presentations | Contributor(s): Timothy D. Sands

    What is a nanowire? What is a nanotube? Why are they interesting and what are their potential applications? How are they made? This presentation is intended to begin to answer these questions while introducing some fundamental concepts such as wave-particle duality, quantum confinement, the...

  19. Scientific Ethics and the Signs of Voodoo Science

    18 Oct 2006 | Online Presentations | Contributor(s): Andrew S. Hirsch

    Until recently, the issue of research ethics had not been a subject of explicit discussion within the Physics community. Over the past ten years, however, documented cases of scientific fraud have brought this issue to center stage. We will explore, through case studies, some examples ranging...

  20. Materials strength: does size matter? nanoMATERIALS simulation toolkit tutorial

    01 Feb 2007 | Online Presentations | Contributor(s): Alejandro Strachan
