Network for Computational Nanotechnology

Structure

The school will consist of two lectures in the morning on the Nanostructured Electronic Devices: Percolation and Reliability and an afternoon lecture on Graphene Physics and Devices. A hands on laboratory session will be available in the afternoons. Participants who complete the series of lectures and exercises will be awarded a certificate of completion.

Morning Sessions

Nanostructured Electronic Devices: Percolation and Reliability
Professor Muhammad A. Alam, School of Electrical and Computer Engineering, Purdue University

Over the course of the 20th century, electronics changed many times. The early focus on radar and radio morphed into the phenomenal rise of computing and communication by 1970s. And today, as the transistors are scaled to their ultimate limit, the remaking of electronics for applications in displays, healthcare, and energy is underway. Each wave of reinvention has dictated the choice of electronic materials i.e. from metals in Klystrons to crystalline semiconductors for computing/communication to amorphous/random materials for solar cells and flexible electronics. As a result, the theoretical treatment of carrier transport in electronic devices and how we design/optimize them continues to evolve. In this series of lectures, Prof. Alam introduces a simple theoretical framework for treating randomness and variability in emerging nanostructured electronic devices for wide ranging applications – all within an unified framework of spatial and temporal percolation. The problems considered involve stochastic defect generation in integrated circuits (i.e. reliability), percolative transport in carbon nanonets for flexible electronics and nanbio sensors, and neo-classical electron/hole diffusion in phase-segregated polymer solar cells, etc.

Afternoon Sessions

Colloquium on Graphene Physics and Devices
Professors Supriyo Datta, Mark Lundstrom, and Joerg Appenzeller, School of Electrical and Computer Engineering, Purdue University

Graphene is a material with interesting electronic properties and one that is currently receiving great attention as a potentially useful material for novel electronic devices. It is also a simple material that provides a concrete example for illustrating how to apply the concepts from electronics from the bottom up to current research problems. The purpose of this short course is to introduce students to this fascinating research topic as well as to develop their skill in problem solving using the tools and techniques of electronics from the bottom up.
