At present, two important development directions of CZT detector are multiple large-volume parallel detectors and surface element array detectors. The former is composed of multiple CdZnTe crystal arrays with a volume greater than 1cm. This type of detector solves the shortcomings of a single detector, which is small in size and low in total detection efficiency, and greatly shortens the measurement time. It is especially suitable for portable spectrometer systems and can be used for radioactive monitoring in the environment, port, railway cargo, etc. The latter is composed of a CdZnTe crystal face element array, and this CZT detector technology is mainly used in energy spectrum imaging in nuclear medicine, astrophysics and other fields.
The development and use of CZT detector has made it possible to obtain high-efficiency photons with high performance. With the continuous improvement of high-quality CdZnTe semiconductor crystal preparation technology, further understanding of the carrier collection process and the development of rapid low-noise microelectronics, CdZnTe detector will surely be applied in a wider fields.

Ge(Germanium) Single Crystals and Wafers
PAM-XIAMEN offers 2”, 3”, 4” and 6” germanium wafer, which is short for Ge wafer grown by VGF / LEC. Lightly doped P and N type Germanium wafer can be also used for Hall effect experiment. At room temperature, crystalline germanium is brittle and has little plasticity. Germanium has semiconductor properties. High-purity germanium is doped with trivalent elements (such as indium, gallium, boron) to obtain P-type germanium semiconductors; and pentavalent elements (such as antimony, arsenic, and phosphorus) are doped to obtain N-type germanium semiconductors. Germanium has good semiconductor properties, such as high electron mobility and high hole mobility. -
