Studies on Crystallization of Pure Boronde in a hydrogen atmosphere. The. powder was then melted in an argon atmosphere by induction heating to form rods. The melt was contained either in quartz boats lined with pure boron nitride or in internally water-cooled silver boats. Single-crystal growth was accomplished without using crucible met

Carbon Determination in Hyperpure Elemental Boron Using Gas Chromatographywith tin powder, which serves as an accelerator, is burned under controlled conditions in an induction-heated furnace. The gaseous products are passed through a molecular sieve column at an initial temperature of 100°C. The carbon dioxide remains trapped in the molecular sieve, while the oxygen is s

Some Results of the Band Structure Calculation of Rhombohedral Boron by the K·p-Methodhedral modifications of boron have such lattices.) The special arrangement of the atoms forming icosahedra is not considered. The possible energy bands can be classified according to their transformation properties under the symmetry operations of .. The K • p-method allows the conclusion that all t

Conductivity, Hall Effect, Optical Absorption, and Band Gap of Very Pure Boron· 10.Ω-cm at 180°C to 2 and 3. 5 · 10.Ω-cm at room temperature. The band gap ∆E., ascertained from the intrinsic range was about 1.42 eV, whereas E.° K obtained from the optical absorption edge was about 1.53 eV. The temperature dependence of the mobility should be more than — 3/2 because of the inf
