Atomically controlled substitutional boron-doping of graphene nanoribbons [PDF]

, 2015
Boron is a unique element in terms of electron deficiency and Lewis acidity. Incorporation of boron atoms into an aromatic carbon framework offers a wide variety of functionality.

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.

The Boron Advantage: The Evolution and Diversification of Boron’s Applications in Medicinal Chemistry

Pharmaceuticals, 2022
In this review, the history of boron’s early use in drugs, and the history of the use of boron functional groups in medicinal chemistry applications are discussed. This includes diazaborines, boronic acids, benzoxaboroles, boron clusters, and carboranes.

Boron-Decorated Pillared Graphene as the Basic Element for Supercapacitors: An Ab Initio Study

Applied Sciences, 2021
In this work, using the first-principle density functional theory (DFT) method, we study the properties of a new material based on pillared graphene and the icosahedral clusters of boron B12 as a supercapacitor electrode material.

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 ...

The Structures and Bonding of Bismuth-Doped Boron Clusters: BiB₄⁻ and BiB₅⁻

Inorganics, 2023
We present an investigation on the structures and chemical bonding of two Bi-doped boron clusters BiBn− (n = 4, 5) using photoelectron spectroscopy and theoretical calculations. The electron affinities of BiB4 and BiB5 are measured to be 2.22(2) eV and 2.

Boron-Based Inverse Sandwich V₂B₇⁻ Cluster: Double π/σ Aromaticity, Metal–Metal Bonding, and Chemical Analogy to Planar Hypercoordinate Molecular Wheels

Molecules, 2023
Inverse sandwich clusters composed of a monocyclic boron ring and two capping transition metal atoms are interesting alloy cluster systems, yet their chemical bonding nature has not been sufficiently elucidated to date.
