Abstract

The invention provides a multi-specification microscope linkage analysis sample table for transmission electron microscope samples. The sample table comprises a unit body, an instrument compatible shell and an assembler. The unit body plays a role in bearing and fixing the TEM grid, the instrument compatible shell has various specifications, the shape of the instrument compatible shell is matched with the used instrument, the unit body can be fixed, then the instrument compatible shell is suitable for different instruments, and combined analysis of various instruments is achieved. Three fixing grooves are formed in the assembler, so that the TEM grid can be directly fixed, and the unit body and the instrument compatible shell can also be fixed. On the basis of the TEM grid, compatibility of different instruments is achieved through the modularized external structure design, and after the TEM grid is installed at a time, only the corresponding instrument compatible shell needs to be replaced, and the sample table can be used among a plurality of instruments in a combined mode. As a universal sample table scheme, the sample table is suitable for the whole process of two-dimensional material transfer preparation, PLM observation, AFM characterization and SEM analysis, the experiment convenience is fully enhanced, and the experiment efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electron microscope analysis, in particular to a multi-specification microscope linkage analysis sample stage for transmission electron microscope samples. Background technique [0002] For sensitive materials, especially sensitive two-dimensional materials, sample preparation and characterization in an inert gas-protected glove box system requires the cooperation of various equipment. Since each equipment comes from different manufacturers, there are differences in specifications, models and application requirements. Therefore, TEM samples need to switch multiple times on different instrument sample stages from preparation to basic characterization analysis. [0003] TEM grid is small in size and fragile in structure, and the steps of preparing TEM samples in the glove box system are complicated and difficult to operate. The prepared samples are located on the TEM grid. Switching the sample stage / cup fo...
