Lightning holder for In Situ TEM Biasing & Heating

Lightning In situ TEM 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.

Why Lightning?

  • Unparalleled capability – Achieve electric fields higher than 300 kV/cm at 900°C
  • Measure sample response – perform thermal studies while simultaneously measuring I-V response with pA current sensitivity
  • High impact results – minimal displacement even at ΔT = 1000°C and minor bulging preserves resolution without tedious stage movements

Lightning key features

Nano-Chip provides attainable E-fields up to 300 kV/cm at 900°C.

Extremely low drift (< 0.5 nm/min) under heat and bias.

Reliable and homogenous temperature: temperature accuracy better than 96% and temperature uniformity better than 98%.

Sample Holders

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
    Collecting high quality data during dynamic in situ explements requires a stable holder. 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 (ThermoFisher) Titan.
  • Large double-tilt range
    Ensure you can reach the zone axis for the sharpest image contrast with our double tilt Lightning HB+ holder. For tilt range specifications, please contact us.
