Using Hummingbird Scientific’s heater chips, researchers can control specimen temperatures in both gas and liquid, as well as in vacuum environments. When stacked together and compressed by o-rings, heater and spacer chips form a space of normal atmospheric conditions between the two chips, called an environmental cell. Environmental cells allow researchers to image specimens in-situ without extensive sample preparation, which helps to limit sample preparation artifacts. Research applications include:
- Kinetics and growth of nano-structures, line nano-articles, and nano-wires
- Reactions of biological structures in liquid environment
- Corrosion processes
Hummingbird Scientific’s heater chips are self-sensing and provide closed-loop in-situ temperature measurements . For liquid holder heater chips, researchers can adjust the temperature from room temperature to the boiling point of the liquid used (up to 200°C). For gas holder and heating+biasing holder heater chips, researchers can adjust the temperature from room temperature to > 1000°C).
Samples can be mounted using:
- FIB cut sample manipulation
- Drop-casting nanostructures
- Direct-deposited local samples (i.e. FIB-deposited, hard-mask shadow deposition)
