Electrical Properties,ever, Be is a good electrical conductor. Its conductivity at room temperature is only four times lower than that of Cu under the same conditions. Two effects contribute to this high conductivity: first, band structure calculations indicate that there is an overlap of the electrons from the first int

At 300 K on polycrystalline Be the Raman line was observed at 455 cm.(line width Δω ≈ 16 cm.) with 4880 Ǻ (Ar ion laser) excitation as the Stokes line . At room temperature on single crystal Be with the polished surface in the crystallographic x-z plane, the line was ob
