__Overview__

Welcome to the Nanoelectronics group! If you are a student or practicing engineer or scientist who wants to learn more about nanoelectronics or an instructor looking for materials to use in a course, you can find material here that includes complete courses and seminars on specialized topics.

Much of the material is freely accessible by any visitor, but by joining this group, you can participate in discussions on topics of interest to you. Additionally, as a group member you may receive notifications about new materials and events of interest to the nanoelectronic group members.

You can also contribute substantial resources to nanoHUB through the resource contribution process, and then send a message to the group manager so that links to those resources can be added to this group.

This group contains the following:

__Introductory Material__

### Along for the Ride: Reflections on the Past, Present, and Future of Nanoelectronics

This presentation is designed for the general audience, and takes a journey through the history of nanoelectronics- explaining some of the challenges the industry faces today in issues such as scaling and power, introduces some novel nanoelectronic devices and speculates on what the future holds.

### Introduction to Carbon Nanotube Electronics

Carbon nanotubes (CNT) have interesting, structure-dependent electronic properties. In particular, CNTs can be a metallic or semiconducting depending on the way in which the carbon atoms are arranged in the CNT walls. The purpose of this learning module is to familiarize students with the basic concepts associated with CNT electronic properties. It begins with a pre-test to assess initial student knowledge of the topic, followed by a presentation and reading material on the electronic properties of CNTs. This is followed by some exercises that utilize the CNTbands tool on the nanoHUB for computing key electronic properties of CNTs. Finally, a post-test is administered to determine the degree to which the module assisted in student learning of the fundamental concepts associated with the electronic properties of CNTs.
