Upgrading of CdZnTe by annealing with pure Cd and Zn metals

A method for the annealing of a CdZnTe crystal is described in this paper. Pure Cd and Zn metals are used as annealing sources, which simultaneously provide exact Cd and Zn equilibrium partial pressures for CdZnTe at a certain temperature. Characterizations reveal that homogeneity is highly improved and the defect densities are decreased by more than one order, and hereby the structural, optical and electrical properties of the CdZnTe crystal are evidently improved by this annealing. Investigation of the temperature dependence of the CdZnTe quality after annealing shows 1073 K to be the preferable annealing temperature for CdZnTe. This annealing process has already been demonstrated to be superior to approximate equilibrium partial pressure annealing by using Cd₁₋_yZn_y alloy as the annealing source.

Improved InAsP metamorphic layers grown on an InP substrate using underlying InP grown at low temperatures

The use of an InP epitaxial layer grown at low temperatures before the growth of a step-graded InAsP metamorphic buffer has been shown to provide a large improvement in the crystal quality of the final metamorphic layer. The improvement is evidenced by over an [...]

Float-Zone Mono-Crystalline Silicon

PAM-XIAMEN can offer float zone silicon wafer, which is obtained by Float Zone method. Monocrystalline silicon rods is got through float zone growth, and then process the monocrystalline silicon rods into silicon wafers, called float zone silicon wafers. Since the zone-melted silicon wafer is not in contact with the quartz crucible during the floating zone silicon process, the silicon material is in a suspended state. Thereby, it is less polluted during the process of floating zone melting of silicon. The carbon content and oxygen content are lower, the impurities are less, and the resistivity is higher. It is suitable for the manufacture of power devices and certain high-voltage electronic devices.

Photo Mask

PAM-XIAMEN Offers Photomasks

A photo mask is a thin coating of masking material supported by a thicker substrate, and the masking material absorbs light to varying degrees and can be patterned with a custom design. The pattern is used to modulate light and transfer the pattern through the process of photolithography which is the fundamental process used to build almost all of today’s digital devices.

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.
