Semiconducting Characteristics of Magnesium-Doped Al2O3 Single Crystals
M. Tardio, R. Ramirez, R. Gonzalez +2
DC and AC electrical measurements were performed to investigate the electrical conductivity of alpha-Al2O3:Mg samples with different concentrations of [Mg]^0 centers .The concentra…
No well-defined remnant Fermi surface in Sr2CuO2Cl2
S. Haffner, D. M. Brammeier, C. G. Olson +2
In angle-resolved photoelectron spectra of the antiferromagnetic insulators Ca2CuO2Cl2 and Sr2CuO2Cl2 a sharp drop of the spectral intensity of the lowest-lying band is observed al…
Electrical Conductivity in Magnesium-Doped Al_2 O_3 Crystal at Moderate Temperatures
M. Tardío, R. Ramírez, R. González +2
AC and DC electrical measurements between 273 and 800 K were used to characterize the electrical conductivity of Al_2 O_3:Mg single crystals containing [Mg]^{0} center. At low fiel…
QSOs and Absorption Line Systems Surrounding the Hubble Deep Field
Daniel E. Vanden Berk, Chris Stoughton, Arlin P. S. Crotts +2
We have imaged a 45x45 sq. arcmin. area centered on the Hubble Deep Field (HDF) in UBVRI passbands, down to respective limiting magnitudes of approximately 21.5, 22.5, 22.2, 22.2,…
