Description

technical field [0001] The invention relates to the technical field of fluid physics, in particular to a liquid bridge generator. Background technique [0002] The floating zone method is a method of growing semiconductor crystal materials. The main principle of the floating zone method is that the material rod is heated by the outside, and the melting zone is supported between two solid material ends, and the heated melting zone is gradually pulled to grow the crystal. The quality is affected by the periodic oscillating capillary convection in the melting zone, which in turn produces micron-scale impurity streaks. The liquid bridge is based on the preparation of single crystals by the floating zone method, and is an ideal physical experimental model established to study the suppression of periodic oscillatory capillary convection during the crystal growth process. [0003] However, the experimental research on the influence of different airflow conditions, temperature cond...

Problems solved by technology

[0003] However, the experimental research on the influence of different airflow conditions, temperature conditions and magnetic field conditions on the liquid bridge interface is still in its infancy, and the few experimental researches cannot be widely promoted because of the complex structure and single function of the liquid bridge generation equipment.
