Abstract

The invention discloses an apparatus and a method used for synthesizing zinc germanium diphosphide polycrystalline. The apparatus comprises a crucible, a heating furnace, and a motor. An explosion-proof steel pipe is arranged in the heating furnace, and the crucible is arranged in the explosion-proof steel pipe. The motor is connected to the inner part of the explosion-proof steel pipe through a linkage bar. According to the invention, the crucible is rotated, such that phosphor can subject to a sufficient reaction, and the yield and the purity of the grown zinc germanium diphosphide polycrystalline are high. Also, the yield of the zinc germanium diphosphide polycrystalline obtained through one time of synthesizing is large. Therefore, the apparatus and the method are suitable to be popularized.

Description

technical field [0001] The invention relates to the technical field of growth of phosphorus-germanium-zinc polycrystals, in particular to a synthesis device and method for phosphorus-germanium-zinc polycrystals. Background technique [0002] Chalcopyrite semiconductor crystals belong to nonlinear optical crystals. It has two outstanding advantages: large nonlinear optical coefficient and wide transmission band in the middle and far infrared region. Zinc germanium phosphide crystal has the best overall performance among chalcopyrite semiconductor crystals. Compared with other chalcopyrite semiconductor crystals, germanium zinc phosphide crystals have their own special properties: 1. Wide transmission band, from 0.7um to 12um; 2. Large nonlinear coefficient; 3. High thermal conductivity, It is not easy to cause damage to the crystal and optical components; 4. The hardness is high, and the crystal has high machining performance. Therefore, the military and civilian prospects...
