Progress in technology has brought microelectronics to the nanoscale, but nanoelectronics is not yet a well-defined engineering discipline with a coherent, experimentally verified, theoretical framework. The NCN has a vision for a new, 'bottom-up' approach to electronics, which involves: understanding electronic conduction at the atomistic level; formulating new simulation techniques; developing a new generation of software tools; and bringing this new understanding and perspective into the classroom. We address problems in atomistic phenomena, quantum transport, percolative transport in inhomogeneous media, reliability, and the connection of nanoelectronics to new problems such as biology, medicine, and energy. We work closely with experimentalists to understand nanoscale phenomena and to explore new device concepts. In the course of this work, we produce open source software tools and educational resources that we share with the community through the nanoHUB.
This page is a starting point for nanoHUB users interested in nanoelectronics. It lists key resources developed by the NCN Nanoelectronics team. The nanoHUB contains many more resources for nanoelectronics, and they can be located with the nanoHUB search function. To find all nanoelectronics resources, search for 'nanoelectronics.' To find those contributed by the NCN nanoelectronics team, search for 'NCNnanoelectronics.'

Quantum Spins in the Solid-State: An Atomistic Material-to-Device Modeling Approach
30 Aug 2017 | | Contributor(s):: Rajib Rahman
In this talk, I will present an atomistic modeling approach that combines intrinsic material and extrinsic device properties under a unified framework to describe spins and their interactions with theenvironment. This approach captures important spin properties such as exchange, spin-orbit,...
Spin-Orbitronics: A Route to Control Magnets via Spin-Orbit Interaction
21 Jul 2017 | | Contributor(s):: Upadhyaya, Pramey
In this talk, I will present this “spin-orbitronic” control for various magnetic systems. In particular, we will focus on the example of spin-orbit-induced manipulation of magnetic domain walls and skyrmions, i.e. particle-like magnetic configurations capable of storing and...
Building a Topological Quantum Computer 101
20 Jun 2017 | | Contributor(s):: Michael Freedman

In this lecture I will review the use of cellulose-based paper as a material in a variety of electronic (and related) applications, including transistors, light emitting diodes, displays, microfluidics. Paper is a very attractive material for many device applications: very low cost, available in...
Topological Spintronics: from the Haldane Phase to Spin Devices
31 Jan 2017 | | Contributor(s):: Nitin Samarth
e provide a perspective on the recent emergence of “topological spintronics,” which relies on the existence of helical Dirac electrons in condensed matter. Spin‐ and angle‐resolved photoemission spectroscopy shows how the spin texture of these electronic states can be engineered...
Modeling of Inter-ribbon Tunneling in Graphene
11 Nov 2016 | | Contributor(s):: Maarten Van de Put, William Gerard Hubert Vandenberghe, Massimo V Fischetti
IWCE presentation. In this paper we investigate the finite-size effect in nano-scaled graphene flakes. Improving on the bulk description, and because the structures are – atomistically speaking – large in size, we use the empirical pseudopotential method.
