Correlations between x-ray response map & infrared transmission image X-ray map shows the degraded regions precisely correspond to Te inclusions on the right IR image shows Te inclusions, which could be identified by composition and shape Very high correlation found for all CZT samples.
Spatial resolution and flux of Synchrotron Light Source required to understand the role of extended defects In the past, small-scale non-uniformities caused by Te inclusions were overlooked because of the wide beams used X-ray maps of a planar detector containing a grain boundary and Te inclusions measured with different beam sizes 400 x 400 µm 2 200 x 200 µm 2 100 x 100 µm 2 50 x 50 µm 2 20 x 20 µm 2 10 x 10 µm 2
