The electronic devices these days have become so small that the number of dopant atoms in the channel of a MOFET transistor, the number of oxide atoms in its gate dielectric, the number silicon- or metal crystals in nanocrystal Flash memory, the number of Nanowires in a flexible nanoNET transistor, the number of crystals in an poly-crystalline transistors, etc. are all finite, and countable. Moreover many devices like super-capacitors and organic solar cells depend on the randomness their morphology to enhance their performance. How should we think about electron transport through such random systems? The traditional approaches based on effective media theory, virtual crystal approximation, or Monte Carlo simulation are generally not very effective in describing such transport well. This short course introduces percolation theory to electrical engineers and device physicists as a powerful technique to handle such stochastically random transport problems of electronic devices.

Many efforts have been made to search for materials that maximize the thermoelectric (TE) figure of merit, ZT, but for decades, the improvement has been limited because of the interdependent material parameters that determine ZT. Recently, several breakthroughs have been reported by applying nanotechnology. To further enhance ZT, a clear understanding of electronic and thermal transport is necessary. The objectives of this thesis are: 1) to evaluate the electronic and thermal performance with a …

For the past few decades, transistors have been continuously scaled. Dimensions are now at the nanoscale, and device performance has dramatically improved. Nanotechnology is also achieving breakthroughs in thermoelectrics, which have suffered from low efficiencies for decades. As the device scale enters the nanometer range and novel device structures are introduced, it becomes essential to revisit the device physics and develop new simulation frameworks to analyze the experimental data and …

\“Thermoelectrics of Roughened Silicon Nanowire Arrays\” The possibility of using silicon as a thermoelectric material for waste heat recovery is technologically significant due to silicon\‘s economy of scale and vast processing knowhow. Patterning silicon as nanowires with roughened sidewalls is shown to enhance the thermoelectric figure-of-merit ZT by order of magnitude compared to the bulk at 300 K. This enhancement is primarily achieved by reduction of thermal conductivity of silicon below …

This presentation will highlight, for nanoelectronic device examples, how the effective mass approximation breaks down and why the quantum mechanical nature of the atomically resolved material needs to be included in the device modeling. Atomistic bandstructure effects in resonant tunneling diodes, ultra-scales Si slabs, Si nanowires, and alloyed quantum dots will be demonstrated in intuitive pictures. The presentation concludes with a brief overview of the empirical tight-binding method that bridges the gap between material science, physics, and electrical engineering for the quantitative design and analysis of nanoelectronic devices.

The goal of this short course is to provide an introduction to the theory and algorithms behind MD simulations, describe some of the most exciting recent developments in the field and exemplify with a few applications applications. The series also includes a tutorial on the nanoMATERIALS simulation tool, an online MD simulation tool available at the nanoHUB. This provides users with a hands-on experience with MD simulations and enables further exploration of some of the concepts described in the lectures.
