Site-controlled formation of single Si nanocrystals in a buried SiO2 matrix using ion beam mixing
Xiaomo Xu, Thomas Prüfer, Daniel Wolf +8
For future nanoelectronic devices - such as room-temperature single electron transistors - the site-controlled formation of single Si nanocrystals (NCs) is a crucial prerequisite.…
Morphology modifcation of Si nanopillars under ion irradiation at elevated temperatures: plastic deformation and controlled thinning to 10 nm
Xiaomo Xu, Karl-Heinz Heinig, Wolfhard Möller +6
Si nanopillars of less than 50 nm diameter have been irradiated in a helium ion microscope with a focused Ne beam. The morphological changes due to ion beam irradiation at room…
Networks of silicon nanowires: a large-scale atomistic electronic structure analysis
Ümit Keleş, Bartosz Liedke, Karl-Heinz Heinig +1
Networks of silicon nanowires possess intriguing electronic properties surpassing the predictions based on quantum confinement of individual nanowires. Employing large-scale atomis…
Si nano-VINe: Electrical Percolation in Quantum-Confined nc-Si:SiO2 Systems
Serim Ilday, Hande Ustunel, F. Ömer Ilday +7
Nanostructures, especially of silicon, are of paramount importance for new generation solar cell applications. The key material requirements for solar cells are good electrical con…
Comparison of Different Parallel Implementations of the 2+1-Dimensional KPZ Model and the 3-Dimensional KMC Model
Jeffrey Kelling, Géza Ódor, Máté Ferenc Nagy +2
We show that efficient simulations of the Kardar-Parisi-Zhang interface growth in 2 + 1 dimensions and of the 3-dimensional Kinetic Monte Carlo of thermally activated diffusion can…
Surface pattern formation and scaling described by conserved lattice gases
Geza Odor, Bartosz Liedke, Karl-Heinz Heinig
We extend our 2+1 dimensional discrete growth model (PRE 79, 021125 (2009)) with conserved, local exchange dynamics of octahedra, describing surface diffusion. A roughening process…
