Liquid sample holder with electrostatic microscope and control method for observing microscopic samples

Abstract

A liquid sample holder with an electrostatic microscope and a control method for adjusting an observation position of a sample to be observed within liquid material. The liquid sample holder includes an upper shell, a lower shell, a limiting layer, and a bearing plate. The upper shell has a thin-film window. The lower shell is aligned with an inner surface of the upper shell, and together they form a sealed cavity filled with liquid material, where a sample to be observed is distributed. The limiting layer and the bearing plate are disposed within the liquid material. The bearing plate locates between the inner surface and the limiting layer. An electron beam generates an electrostatic force that acts on the sample to be observed, the bearing plate, and the 10 limiting layer, thereby attracting the sample to move to a predefined observation area while the limiting layer move towards the inner surface.
