Boron is a group 13 main-group element (atomic number 5) characterized by electron deficiency, leading to extensive multicenter bonding and a rich structural chemistry. In materials science and solid-state chemistry, boron forms diverse allotropes, including icosahedral cluster-based crystalline phases with high hardness and thermal stability. Its trivalent nature enables formation of covalent networks, borides, borates, and boron-rich ceramics critical in high-temperature and neutron-absorbing applications. In coordination and organoboron chemistry, boron’s Lewis acidity underpins reactions such as hydroboration and its role in frustrated Lewis pair systems, making boron central to catalysis, electronic materials, and functional inorganic frameworks.
Substitutional doping from foreign elements stands out as a preferred method for precisely tailoring the electronic band structure, conduction type, and carrier concentration of pristine materials. In the realm of three-dimensional ...
