Hydrogenation, dehydrogenation of -tetragonal boron and its transition to -orthorhombic boron
Naoki Uemura, Koun Shirai, Jens Kunstmann +2
Boron bulk crystals are marked by exceptional structural complexity and unusual related physical phenomena. Recent reports of hydrogenated -tetragonal and a new -orthorhombic…
