How it works

The TEM Optical Gas Heating Sample Holder integrates fiber-optic illumination, a sealed environmental cell, multifunctional microfabricated MEMS chips, electrical biasing, and dedicated control hardware into a unified platform for photo-assisted in-situ TEM and STEM experiments. An optical fiber is integrated into the holder tip, delivering light directly adjacent to the gas-cell to maximize optical intensity at the specimen while minimizing transmission losses. This architecture enables efficient illumination using standard laboratory light sources while preserving high-resolution TEM/STEM imaging and analytical performance.

‍

The specimen is enclosed within a sealed environmental cell formed by two microfabricated silicon chips with electron-transparent silicon nitride (SiN) windows. Controlled gas flow up to 2 bar, closed-loop MEMS heating beyond 1000 °C, integrated four-point temperature sensing, and electrical biasing can be applied simultaneously during imaging. Compatible MEMS chips and optional multi-channel gas delivery enable researchers to correlate optical, thermal, and electrical stimuli with atomic-scale structural and chemical evolution during in-situ gas-phase TEM experiments.
