Study of fluorine behaviour in silicon by selective point defect injection

open access: yes, 2005
This letter reports a point defect injection study of 185 keV 2.3x1015cm?2 fluorine implanted silicon. After an inert anneal at 1000°C, fluorine peaks are seen at depths of 0.3Rp and Rp and a shoulder between 0.5–0.7Rp.

The chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds

open access: yes, 2005
We present a theoretical investigation of the chemistry of fluorine-bearing molecules in diffuse and dense interstellar gas clouds. The chemistry of interstellar fluorine is qualitatively different from that of any other element, because - unlike the ...

NPBS Atlas: a comprehensive data resource for exploring the biological sources of natural products

open access: yesJournal of Cheminformatics
Natural products continue to play a pioneering role in drug discovery due to their extraordinary chemical and biological diversity. However, their full therapeutic potential remains largely underutilized, hindered by the fragmented documentation of ...

Behaviour and effects of fluorine in annealed n+ polycrystalline silicon layers on silicon wafers

open access: yes, 2000
A comprehensive study is made of the behaviour and effects of fluorine in n+ polysilicon layers. Sheet resistance, TEM and SIMS are used to obtain quantitative data for the breakup of the interfacial oxide, the epitaxial regrowth of the polysilicon and ...

Effects of three-nucleon forces and two-body currents on Gamow-Teller strengths [PDF]

open access: yes, 2014
We optimize chiral interactions at next-to-next-to leading order to observables in two- and three-nucleon systems, and compute Gamow-Teller transitions in carbon-14, oxygen-22 and oxygen-24 using consistent two-body currents.

Step-Wise Computational Synthesis of Fullerene C60 derivatives. 1.Fluorinated Fullerenes C60F2k

open access: yes, 2009
The reactions of fullerene C60 with atomic fluorine have been studied by unrestricted broken spin-symmetry Hartree-Fock (UBS HF) approach implemented in semiempirical codes based on AM1 technique. The calculations were focused on a sequential addition of
