- *Abstract
-
Northwestern researchers have developed new thallium, bismuth or lead chalcohalides for radiation detection, such as that used in biomedical x-ray imaging. The structure of these halides yields improved mechanical and electrical properties in comparison to other materials currently in use (band gap of at least 1.5eV and resistivity of 106 Ωcm). All of the novelchalcohalides exhibit favorable crystal growth and can be made into thin filmsfor various electronic devices. Therefore, these novel materials hold promiseto revolutionize the field of radiation detection, whether for medical ordefense purposes.
