Special interest has developed the CdZnTe system; known to be a good
candidate for lattice matched substrate for growth of Hg Cd Te and Hg Zn
Te epitaxial thin films. In addition CdZnTe and CdTe crystals are
important materials for the development of high - resolution for
infrared and radiation detectors. However, CdTe suffers from weak
collection efficiency and high impurity and native defect densities,
which favored CdZnTe as more attractive material for such nuclear
applications. In order to obtain a technologically competitive material,
it is necessary to grow the material, study and then controls the effect
of impurities and native defects on the electrical and other properties
of the material.As a consequence of suppression of crystal - crucible
interaction, most of the crystals grown in space have shown a better
structural quality than crystals obtained on the earth under the same
conditions.
