Reduction of boron diffusion in silicon-germanium by fluorine implantation

, 2004
This paper investigates the effect of a 185 keV, 2.3×1015cm-2 F+ implant on boron thermal diffusion and boron transient enhanced diffusion (TED) in SiGe by characterising the diffusion of a boron marker layer in samples with and without a 288 keV, 6 ...

Effects of water and fluorine on the viscosity of albite melt at high pressure: a preliminary investigation [PDF]

, 1985
The viscosities of fluorine- and water-bearing melts based on albite composition have been determined at 7.5, 15 and 22.5 kbar by the falling-sphere method. All melt viscosities decrease isothermally with increasing pressure.

Electrocatalytic conversion of lithium polysulfides by highly dispersed ultrafine Mo2C nanoparticles on hollow N‐doped carbon flowers for Li‐S batteries

EcoMat, 2020
The significant challenge in exploring novel nanostructured sulfur host materials for Li‐S batteries is to simultaneously mitigate the notorious shuttle effect and catalytically enhance the redox kinetics of lithium polysulfides (LPSs).

Hot-Carrier Stressing of NPN Polysilicon Emitter Bipolar Transistors Incorporating Fluorine

, 2003
The effects of fluorine on the hot-carrier induced degradation in low-thermal-budget polysilicon emitter NPN bipolar transistors have been examined. Forward Gummel plots, base emitter (BE) diode characteristics, and stress currents were measured during ...

Fluorine in silicate glasses: A multinuclear nuclear magnetic resonance study [PDF]

, 1992
Anhydrous nepheline, jadeite, and albite glasses doped with F as well as hydrous F-containing haplogranitic glasses were investigated using 19F combined rotation and multiple-pulse spectroscopy; 19F → 29Si cross-polarization/magic angle spinning (MAS ...

Can fluorine form triple bonds? [PDF]

, 2022
A central dogma is that fluorine is the most electro negative element in the PSE and would thusact as a pure electron acceptor. However, to some chemists it is known, that fluorine can bond induality.
