Grundlagen der Objektorientierung,vestigation has the composition Al.C.B., are discussed. It is possible to prepare tetragonal boron from BeB 12 by the topochemical substitution reaction . A similar reaction of BeB. with SiCl. yields a boride (Be, Si) B.. This boride can be recrystallized from molten aluminum in the form of single c

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

Christian Damböck,Meike G. Werner· 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
