Atomistic Calculations Predict Boron Incorporation Increases Leds

High-power white LEDs face the same problem that Michigan Stadium faces on game day — too many people in too small of a space. Of course, there are no people inside of an LED. But there are many elect...
Emergence of step flow from an atomistic scheme of epitaxial growth in 1+1 dimensions
step flow atomistic scheme epitaxial growth 1+1 dimensions
2015/10/16
The Burton-Cabrera-Frank (BCF) model for the flow of line defects (steps) on crystal surfaces has offered useful insights into nanostructure evolution. This model has rested on phenomenological ground...
Atomistic simulations of electrolyte solutions and hydrogels with explicit solvent models
Atomistic simulations electrolyte solutions hydrogels explicit solvent models
2011/8/11
Abstract: Two of the most challenging tasks in molecular simulation consist in capturing the properties of systems with long-range interactions (e.g. electrolyte solutions) as well as systems containi...
On the passage from atomistic systems to nonlinear elasticity theory
nonlinear elasticity theory Analysis of PDEs
2011/9/16
Abstract: We derive continuum limits of atomistic models in the realm of nonlinear elasticity theory rigorously as the interatomic distances tend to zero. In particular we obtain an integral functiona...
Atomistic Molecular Dynamics Simulations of Shock Compressed Quartz
Shock wave Molecular Dynamics BKS potential Quartz
2011/8/4
Abstract: Atomistic non-equilibrium molecular dynamics (NEMD) simulations of shock wave compression of quartz have been performed using the so-called BKS semi-empirical potential of van Beest, Kramer ...
Atomistic theory of spin relaxation in self-assembled In$_{1-x}$Ga$_x$As/GaAs quantum dots at zero magnetic field
Atomistic theory spin relaxation zero magnetic field
2010/11/25
We present full atomistic calculations of the spin-flip time (T1) of electrons and holes mediated by acoustic phonons in self-assembled In1−xGaxAs/GaAs quantum dots at zero magnetic field. At lo...
Large enhancement in hole velocity and mobility in p-type [110] and [111] silicon nanowires by cross section scaling: An atomistic analysis
silicon nanowire mobility p-type holes atomistic bandstructure
2010/11/22
The mobility of p-type nanowires (NWs) of diameters of D=12nm down to D=3nm, in [100], [110], and [111] transport orientations is calculated. An atomistic tightbinding model is used to calculate the N...
Think small! Think quickly! Atomistic model helps students visualize nanoscale problems
Civil and Environmental Engineering quantum mechanics

April 2, 2007,Civil engineers by tradition are concerned with the big picture, but some are refocusing their vision, zooming in to solve minute problems we can't see with the naked eye, like tiny frac...
