| Outline of Final Research Achievements |
Development of X-ray detectors using a compound semiconductor, thallium bromide (TlBr), was performed for realizing high-sensitive flat-panel detectors. High-pure TlBr was obtained by the horizontal zone purification method. Small pixel electrodes were formed successfully on TlBr single crystals. Thin-film detectors were fabricated from TlBr thin films deposited on ITO glass substrates by the vacuum evaporation method. The fabricated thin films exhibited high resistivity at room temperature.
