X-ray emission from LiTaO3 induced by thermal changes and structure analysis

X-ray emission from LiTaO3 induced by the thermal changes from about 300-480K has been investigated in a vacuum system. The single-crystal X-ray structure analysis of LiTaO3 was carried out at 269, 286, 303, 319, 337, 358, 381, 413, and 436K, respectively, far below the phase transition (930K). The...

Description
Summary:X-ray emission from LiTaO3 induced by the thermal changes from about 300-480K has been investigated in a vacuum system. The single-crystal X-ray structure analysis of LiTaO3 was carried out at 269, 286, 303, 319, 337, 358, 381, 413, and 436K, respectively, far below the phase transition (930K). The relationship between the observed X-ray emission and the pyroelectric coefficient of LiTaO3 is discussed.
