The entire tube spectrum is polarized by the low atomic number secondary target and is available to excite the sample, but this polarized beam cannot (in an ideal geometric arrangement) be scattered off the sample into the detector. If, therefore, the metal target (in the secondary target ED-XRF configuration, Fig. 3) is replaced by a low atomic number target such as boron carbide (or corundum), the benefits of polarization can be achieved, without interference from nonpolarized secondary target lines. Low atomic number materials are more efficient at scattering X-rays than higher atomic materials.

Results have been published, which show that the (111) surface has the highest hardness value ( Zhang et al., 2008b). In general, the energy of defect formation increases with the addition of Zn ( Owens et al., 2002). The incorporation of Zn into the CdTe structure strengthens the crystal lattice ( Szeles, 2004), and considering that the Zn–Te ionicity is smaller than the Cd–Te ionicity, but the Zn–Te binding energy is higher, the stability of the compound increases as well as the shear modulus, while the densities of dislocations and subgrains are reduced ( Triboulet, 2005). This property leads to higher collection efficiency ( Duff et al., 2008) as the interactions between the crystal lattice and incoming radiation are increased.
Although there is some discrepancy among authors, values between 5.8 and 6.68 g cc −1 ( Lun et al., 2006 Mandal et al., 2007) have been reported for CZT. CZT materials have a density of nearly 6 g cc −1 ( Auricchio et al., 2008 Fiederle et al., 2004 Goswami et al., 2005 Horodysky et al., 2006 Mandal et al., 2007 Marchini et al., 2008), which provides greater stopping power against incoming γ-rays than competing material technologies. One advantage of using CZT as a detector for high-energy radiation is the high average atomic number of Z = 50, compared with other well-known detector materials such as silicon and germanium with Z = 14 and Z = 32, respectively.ĭensity.
