Abstract
Device and method for immersed synthesis and continuous growth of phosphides under a magnetic field are disclosed in the field of semiconductor material preparation. In particular, device and method for synthesizing and growing semiconductor phosphides by means of immersing phosphorus into a metal melt under the action of a static magnetic field are disclosed. The device includes a furnace body, an injection synthesis system and a static magnetic field generator. The method includes A, heating the crucible to melt the metal and a covering material boron oxide in the crucible; B, immersing red phosphorus into the crucible; C, applying a static magnetic field surrounding the crucible, and adjusting the temperature gradient to start the synthesis; and D, performing crystal growth after completion of the synthesis. With the method provided by the present invention, the red phosphorus sinks into the melt in the form of a solid and floats upward from the bottom of the crucible after gasification, solving problems such as sucking-back generated by use of phosphorus bubbles; the transverse static magnetic field suppresses the bubble up-floating rate while suppressing the melt convection in the direction of the temperature gradient, so that the synthesis process is smoother and more rapid.
