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 ...

110GHz fT Silicon Bipolar Transistors Implemented using Fluorine Implantation for Boron Diffusion Suppression

, 2006
This paper investigates how fluorine implantation can be used to suppress boron diffusion in the base of a double polysilicon silicon bipolar transistor and hence deliver a record fT of 110 GHz.

Effect of Fluorine Implantation Dose on Boron Transient Enhanced Diffusion and Boron Thermal Diffusion in Si1-xGex

, 2005
This paper studies how boron transient enhanced diffusion (TED) and boron thermal diffusion in Si1-xGex are influenced by a high-energy fluorine implant at a dose in the range 5 × 1014 cm-2 to 1 × 1016 cm-2.

High levels of boron promote anchorage-independent growth of nontumorigenic cells [PDF]

, 2020
WHO has presented a health-based guideline value for boron in drinking water. That fact indicates that a high level of boron is toxic for humans. However, there is no direct evidence of boron-mediated malignant transformation.

Fast and accurate electronic structure methods : large systems and applications to boron-carbon heterofullerenes [PDF]

, 2013
The interactions among electrons and nuclei, which are the constituents of matter, are governed by the fundamental laws of quantum mechanics. Methods that use these laws in order to determine the properties of matter are called ab-initio approaches ...

Quantifying microhabitat selection of snowshoe hares using forest metrics from UAS‐based LiDAR

Wildlife Biology, Volume 2026, Issue 5, September 2026.
Identifying the spatial and temporal scale at which animals select resources is critical for predicting how populations respond to changes in the environment. The spatial distribution of fine‐scale resources (e.g. patches of dense vegetation) are often linked with critical life‐history requirements such as denning and feeding sites.
