Ion-implantation induced anomalous surface amorphization in silicon [PDF]

open access: yes, 1994
Spectroscopic ellipsometry (SE), high-depth-resolution Rutherford backscattering (RBS) and channeling have been used to examine the surface damage formed by room temperature N and B implantation into silicon.

Sub-unit cell layer-by-layer growth of Fe3O4, MgO, and Sr2RuO4 thin films

open access: yes, 2002
The use of oxide materials in oxide electronics requires their controlled epitaxial growth. Recently, it was shown that Reflection High Energy Electron Diffraction (RHEED) allows to monitor the growth of oxide thin films even at high oxygen pressure ...

Building biomedical materials layer-by-layer [PDF]

open access: yes, 2012
In this materials perspective, the promise of water based layer-by-layer (LbL) assembly as a means of generating drug-releasing surfaces for biomedical applications, from small molecule therapeutics to biologic drugs and nucleic acids, is examined ...

Carrier scattering, mobilities and electrostatic potential in mono-, bi- and tri-layer graphenes

open access: yes, 2009
The carrier density and temperature dependence of the Hall mobility in mono-, bi- and tri-layer graphene has been systematically studied. We found that as the carrier density increases, the mobility decreases for mono-layer graphene, while it increases ...

Numerical test of the damping time of layer-by-layer growth on stochastic models

open access: yes, 1998
We perform Monte Carlo simulations on stochastic models such as the Wolf-Villain (WV) model and the Family model in a modified version to measure mean separation $\ell$ between islands in submonolayer regime and damping time $\tilde t$ of layer-by-layer ...

Antimony doping of Si layers grown by solid-phase epitaxy [PDF]

open access: yes, 1976
We report here that layers of Si formed by solid-phase epitaxial growth (SPEG) can be doped intentionally. The sample consists initially of an upper layer of amorphous Si (~1 µm thick), a very thin intermediate layer of Sb (nominally 5 Å), and a thin ...
