“…We noted that our study findings differ from those of Zeng et al (2009), who examined abrupt, large-scale twin boundaries and sub-boundary networks with bulk CZT grown using the MVB method with HR-TEM. Our observations examined differences on the atom scale rather than that on the larger 200 to 1000 nm scale.…”

“…Transmission electron microscopy (HR-TEM) has been used to examine the atom scale defects in SP and the bulk of CZT [1,5,6,7]. The morphology and crystalline plane orientation of the SP that consisted of dendritic and Te-rich material in CZT have been investigated in a highly detailed study using scanning electron microscopy (SEM) and electron backscatter diffraction (EBSD) [8].…”

“…Both experimental and simulation results showed the severe performance degradation of the device performance due to the presence of Te inclusions of different size distribution and concentrations 21 . It is to be noted that the sub-grain boundaries were also found to be decorated with the Te inclusions/precipitates 10,22 . Though the Te inclusions can be eliminated by annealing under cadmium vapor, the process produces star-like defects that are not visible in infra-red (IR) transmission microscopy.…”

“…The other major drawback with CZT is the sub-grain boundary network. The sub-grain boundaries are generally individual dislocations arranged in planes, called dislocation walls, and are heavily distributed in the bulk of the CZT matrix 18 , 19 . It is known that the sub-grain boundaries can be formed in CZT ingots due to the thermal stress during crystal growth and subsequent cooling process 19 .…”
