Description
technical field [0001] The invention belongs to the technical field of processing polysilicon light-trapping microstructure particle bubbles, and in particular relates to a device for measuring the chargeability of ultrasonic microbubbles. Background technique [0002] The silicon wet etching reaction is actually an ion reaction, but the movement of the ions is random and uncertain. If the movement of the reaction ions in the solution is not accurately controlled, it is difficult to achieve the precise formation of the controlled morphology. [0003] Ion bubbles can solve the above problems. When microbubbles are generated by ultrasound, the charging characteristics of the microbubbles are changed by related means to absorb reactive ions. Microbubbles can be regarded as particles from a macroscopic perspective. The position of microbubbles in the solution is controlled by the principle of ultrasonic standing waves. When the microbubbles break, the effective ions they carry a...
