About CZT Detectors
Cadmium Zinc Telluride is a wide band gap semiconductor that is fabricated
into detectors that provide two key advantages for use in portable instrumentation.
The high density of the crystal provides excellent stopping power over
a wide range of energies. The ability to operate at room temperature without
the need for liquid nitrogen cooling allows the construction of compact
devices. The resolution of CZT is intermediate between Scintilators and
Germanium devices (sample spectra). Recent
advances in the understanding of crystal growth and detector fabrication
using CZT hold the promise of providing low cost high resolution detectors.
CZT detectors can be fabricated into a variety of shapes and sizes making
it possible to produce detectors capable of meeting the requirements of
a wide assortment of applications unsupported by the other detector types.
In many instances, CZT detectors can be substituted for other detector
types in existing applications
