Pre-Cryogenic Electron Microscope Specimen Holder

摘要

A pre-cryogenic electron microscope specimen holder is disclosed. The pre-cryogenic electron microscope specimen holder includes a specimen holding member and a cryogenic energy storing member. The cryogenic energy storing member further includes a liquid gas storing trench formed therein to store the liquid gas. The cryogenic energy storing member is disposed under the specimen holding member to further supply the cryogenic energy to the specimen to extend the observation time for the specimen in an electron microscope.
