Abstract
330,000 users visited nanoHUB in the past year to learn about and do research using 330 nanotechnology simulation tools and 4,200 resources. The NEMO NanoElectronicsMOdelling engines power several of these Rappture based nanoHUB tools, each with a focus on the study of electronic properties of nanoscale devices. Crystal Viewer, Brillouin Zone Viewer and Bandstructure Lab are used by students to interactively learn about nanoelectronic fundamentals. Tools such as 1DHetero, Quantum Dot Lab, and RTDNEGF provide a means to investigate specialized device structures such 1-D heterostructures, quantum dots, and resonant tunneling diodes, respectively. A set of tools (Nanowire, OMEN_Nanowire, OMEN_FET and nanoFET) are available to investigate characteristic of transistors. A forthcoming tool will allow nanoHUB users to reproduce values in the the International Technology Roadmap for Semiconductors, an industry guide for future device designs and fabrication technologies. Altogether these tools have nearly 20,000 unique users and over 330,000 simulation runs powered by the nanoHUB infrastructure. Computationally intense simulations offload jobs to Purdue's RCAC computing clusters. An in-house testing system has been designed to ensure tools continue to work with continual improvements in the NEMO engines and to ensure maintainability over the course of multiple tool development cycles.

Jim Fonseca is a research scientist in the iNEMO group for nanoelectronics modeling in the Network for Computational Nanotechnology at Purdue University. He received his PhD in Electrical and Computer Engineering from Ohio University in 2008. He helps to develop the group's nanoelectronics software and nanoHUB-based tools using the NEMO5 engine. Before that he researched the ionic selectivity and permeation properties of membrane proteins using reduced-model and molecular dynamics simulations.
