(a) Two CZT crystals are assembled to flexible circuit and stacked based on anode–cathode–cathode–anode configuration to form a CZT module ($4\mathrm{cm}\times 4\mathrm{cm}\times 1\mathrm{cm}$). (b) Schematic of a CZT crystal with cross-strip pattern showing anodes, cathodes, and steering electrodes. (c) Drawing of cross-section of the CZT crystal.
