Atomistic simulations of nucleosomes

WIREs Computational Molecular Science, 2013
AbstractNearly a dozen all‐atom molecular dynamics (MD) simulations of the nucleosome have been performed. Collectively, these simulations provide insights into the structure and dynamics of the biomolecular complex that serves as the fundamental folding unit of chromatin.

Atomistic Simulations on Reliability

2014
Discrete impurity effects in terms of their statistical variations in number and position in the inversion and depletion region of a MOSFET, as the gate length is aggressively scaled, have recently been researched as a major cause of reliability degradation observed in intra-die and die-to-die threshold voltage variation on the same chip resulting in ...

Atomistic simulation of nanodevices

2016 International Conference on Simulation of Semiconductor Processes and Devices (SISPAD), 2016
As the dimensions of electronic devices, especially transistors, are getting smaller and smaller, novel modeling approaches must be developed to reveal the physics and predict the performance of not-yet-fabricated ultra-scaled components. In this paper the basic requirements to simulate nanoscale devices are first reviewed before introducing a ...

Atomistic Nanodevice Simulation

Solid State Phenomena, 2005
There now a large variety of methods exists for the elaboration of nanoobjects and nanodevices. At the same time the reduction in size together with the improvement of theoretical techniques and computational power should allow efficient quantitative simulation of these objects. Such predictive simulation is highly needed since it can serve as a useful

Atomistic Simulations Methods

2015
Atomistic simulations are theoretical and computational modeling tools for interpreting what happens at the atomic scale in solids, liquids, molecules and plasmas. Atomistic simulations, such as phonon calculations, free-energy optimizations (molecular mechanics), molecular dynamics (MD), Monte Carlo simulations, and crystal structure prediction, are ...

‘Atomistic’ simulation of ultra-submicron MESFETs

Microelectronics Journal, 2003
The effects of a discrete random dopant distribution on the MESFET characteristics were investigated using device simulation. The first three moments of the Boltzmann equation coupled to the Poisson equation are solved self-consistently. The model accounts for hot-electron effects, degeneracy and surface-states effects.

Atomistic Simulation on Indented Defects in Silicon

Journal of Nanoscience and Nanotechnology, 2013
Silicon is known as one of the widely used materials in electronic fields for its excellent semiconductive characteristics. However, these characteristics are vulnerable to internal defects, which randomly exist in any materials. In the present study, defects in single crystalline silicon thin film were investigated by atomistic simulation of nano ...

Fundamentals of Atomistic Simulations

2006
Fundamentally, materials derive their properties from the interaction between their constituent atoms. These basic interactions make the atoms assemble in a particular crystalline structure. The same interactions also define how the atoms prefer to arrange themselves in the dislocation core.
