摘要：
The single-crystal TlBr, a promising candidate as gamma-ray detector, is annoyed by material problems. These problems are manly arisen from purity and quality of the crystal, and the total process of detector manufacturing. In this work, the making of electric contact with different methods was studied. Al, Ti, Cr, Fe, Ni, In, Sn, as well Ag and graphite paste were used for annealed TlBr single crystals. Samples were characterised by I-V measurements and routinely studied by optical, X-ray powder diffraction and rocking curve methods. (c) 2006 Elsevier B.V. All rights reserved.
