TEM Gas Plasma Sample Holder

Operando heating, biasing under environmental conditions

Operando Gas Plasma TEM Experiments

The TEM Gas Plasma Sample Holder enables in situ and operando observation of plasma–material interactions inside a transmission electron microscope. The holder supports controlled gas plasma experiments for researchers studying catalyst behavior, nanoparticle reactions, thin-film processes, surface modification, semiconductor materials, and plasma-assisted materials transformations.

‍

Controlled Plasma, Gas, and Heating at the Sample

The system uses a plasma/gas cell architecture with cathode and anode chips, spacers, controlled gas delivery, purge capability, top-to-bottom plasma geometry, plasma voltage above 1 kV, and heating above 1000 °C. This allows researchers to study plasma-driven reactions under defined environmental and thermal conditions.

‍

Workflow Integration for Analytical TEM

The holder is designed for Thermo Fisher Scientific and JEOL TEM platforms and supports EELS/EDS-compatible workflows. Hummingbird connects holder design, sample chips, gas control, TEM safety preparation, and direct engineering support for specialized plasma TEM experiments.
