  1. Fundamentals of Current Flow

    Papers | 30 Jan 2022 | Contributor(s):: Supriyo Datta

    Everyone is familiar with the amazing performance of a modern smartphone, powered by a billion-plus nanotransistors, each having an active region that is barely a few hundred atoms long. The same amazing technology has also led to a deeper understanding of the nature of current flow and heat...

  2. IWCN 2021: Thermoelectric Properties of Complex Band and Nanostructured Materials

    Online Presentations | 14 Jul 2021 | Contributor(s):: Neophytos Neophytou, Patrizio Graziosi, Vassilios Vargiamidis

    In this work, we describe a computational framework to compute the electronic and thermoelectric transport in materials with multi-band electronic structures of an arbitrary shape by coupling density function theory (DFT) bandstructures to the Boltzmann Transport Equation (BTE).

  4. Low Temperature Enhancement of the Thermoelectric Seebeck Coefficient in Semiconductor Nanoribbons

    Online Presentations | 09 Nov 2016 | Contributor(s):: Kommini Adithya, Zlatan Aksamija

    IWCE 2015 Presentation. We propose a novel approach to achieving a narrow window-shaped TDF through a combination of a step-like 2-dimensional density-of-states (DOS) and inelastic optical phonon scattering. A shift in the onset of scattering with respect to the step-like DOS creates a TDF which...

  9. Device Physics Studies of III-V and Silicon MOSFETS for Digital Logic

    Papers | 25 Jun 2013 | Contributor(s):: Himadri Pal

    III-V's are currently gaining a lot of attraction as possible MOSFET channel materials due to their high intrinsic mobility. Several challenges, however, need to be overcome before III-V's can replace silicon (Si) in extremely scaled devices. The effect of low density-of-states of III-V materials...

  10. Direct Solution of the Boltzmann Transport Equation in Nanoscale Si Devices

    Papers | 27 Jun 2013 | Contributor(s):: Kausar Banoo

    Predictive semiconductor device simulation faces a challenge these days. As devices are scaled to nanoscale lengths, the collision-dominated transport equations used in current device simulators can no longer be applied. On the other hand, the use of a better, more accurate Boltzmann Transport...

  11. Two-Dimensional Scattering Matrix Simulations of Si MOSFET'S

    Papers | 27 Jun 2013 | Contributor(s):: Carl R. Huster

    For many years now, solid state device simulators have been based on the drift-diffusion equations. As transistor sizes have been reduced, there has been considerable concern about the predictive capability of these simulators. This concern has lead to the development of a number of simulation...
