In Situ TEM Solutions
Lightning | Biasing & Heating
The Lightning in situ TEM biasing and heating solution allows microscopists to observe real time dynamics of functional nanomaterials under controlled and repeatable electrical and thermal stimuli. A state-of-the-art Nano-Chip accurately controls heat and bias while collecting meaningful sample data. With the possibility to sustain the highest electrical fields and temperatures, individually or simultaneously, a wide range of phenomena now becomes accessible.

Additional Modular Details
The sample holder brings the Nano-Chip into the TEM. Made from titanium for its optimal mechanical stability, the sample holder is carefully designed to integrate into ThermoFisher or JEOL microscopes.
- High stability
The Lighning holder demonstrates less than 200 nm of displacement and a short stabilization time even at temperature swings approaching 1000°C, as well as atomic resolution routinely achievable even at high electric fields.
- Compatible with small pole-piece gaps
The Lightning holder can fit in the smallest pole-piece gaps such as the JOEL ARM and the FEI (Thermo Fisher Scientific) Titan.
- Large double-tilt range
Ensure you can reach the zone axis for the sharpest image contrast with the double tilt Lightning holder. For tilt range specifications, please contact us.
FIB Stub 3.0
The 3rd generation FIB Stub enables an easier, safer, and quicker preparation of lamella. It is designed to allow the user to prepare a lamella and place it directly on the Nano-Chip, all inside the FIB-SEM.
- Ease of use
The sample is located on a flat surface at the top of the stub. This conventional geometry means that the same, well-known process can be used by any FIB operator to prepare the specimen.
- Improved imaging
Reduced shadowing and charging improves image quality, especially at low accelerating voltages during the final milling and polishing steps (1-5 kV).
- Smart clamping
Using the dedicated pocket for the Nano-Chips, loading and unloading becomes a precise and easy process. There is no need for sticky tapes to fix the chip on the sub, minimizing the possibility of damage to the fragile window membranes and chips during handling.
- Safe procedure
Design such that the position of the sample and Nano-chip are at the same height. This minimizes the possibility of crashing into the pole piece, the gas injection system, or the manipulator.
