nanoHUB@SIU: Pedagogy and Beyond
22 Jan 2016 | Online Presentations | Contributor(s): Shaikh S. Ahmed
As a postdoctoral researcher at NCN, during the years 2005-7, in addition to usual research activities, I was tasked with working closely with the nanoHUB Team to augment a few pre-existing quantum device simulators, create rappturized user interfaces, and run end-to-end simulations for scientific validation. These routine yet tedious pieces of work consumed quite a bit of my time and often I was dubious about the outcomes. However, these initial doubts of mine began to fade out after I...
GaN/InGaN/GaN Disk-in-Wire Light Emitters: Polar vs. Nonpolar Orientations
25 Nov 2015 | Online Presentations | Contributor(s): Rezaul Karim Nishat, S. Alqahtani, Ye Wu, Vinay Uday Chimalgi, Shaikh S. Ahmed
IWCE 2015 presentation. in this paper, we computationally evaluate and compare the performance of recently reported in0.75n/gan disk-in-wire light emitting diodes (led) grown in the polar (c-plane) and nonpolar (m-plane) crystallographic orientations in terms of built-in fields, electronic bandstructure and interband optical transition rates. the microscopically determined transition parameters were then incorporated into a TCAD LED simulator to obtain the device terminal...

MOSCap Tool on nanoHUB.org
The primary reason to study MOS (metal-oxide-semiconductor) capacitors is to understand the principle of operation as well as become familiar with some of the routinely used characterization techniques for MOS field effect transistors (MOSFETs). The MOSCap tool on nanoHUB.org simulates the...
Primer on the MOSFET Simulator on nanoHUB.org
The MOSFET simulator on nanoHUB.org (http://nanohub.org/resources/mosfet) simulates the equilibrium electrostatics and non-equilibrium current-voltage (I-V ) characteristics of i) bulk, ii) dual-gate, and iii) SOI based field efect transistors. In this chapter, we will describe: i) the...
