Dielectric Properties of Multi-Layers Hexagonal Boron …

Boron Nitride is isoelectronic to carbon and it has two major allotropes: hexagonal boron nitride (h-BN) that is similar to graphite while cubic boron nitride (c-BN) which resembles to diamond [1]. BN is produced unnaturally by boric acid or boron trioxide. Amorphous BN powder was initially produced, that is converted to crystalline like h-BN ...

Electronic structure of diatomic boron nitride - …

BN molecules, isoelectronic with C 2 , are produced by laser vaporization of boron nitride and trapped in solid neon. Through Fourier-transform absorption and laser-induced fluorescence spectra, three new electronic states are observed. Unlike C 2 , BN has a triplet ground state (X 3 Π), but with an exceedingly low-lying singlet (a ¹∑⁺) state with 15 cm^-1< ...
