Hummingbird Scientific’s Cryo-Biasing TEM Sample Holder enables researchers to conduct in-situ electrical biasing experiments of materials at cryogenic temperatures. The combination of the liquid-nitrogen Dewar with a built in heater allows the temperature of the sample to be set at a desired range and controlled with closed-loop controller from -170C to room temperature.
Example research applications of this holder include transport measurements in quantum materials like:
- Emergent monopoles
- Topological insulators
