Temperature Calibration for In Situ Environmental Transmission Electron Microscopy Experiments

Abstract
In-situ Environmental Transmission Electron Microscopy (ETEM) experiments require specimen heating holders to study material behavior in gaseous environments at elevated temperatures. For these experiments it would be useful to have a direct measurement of local sample temperature, particularly when room temperature gasses are introduced in the sample area. Using selected-area diffraction (SAD) in an ETEM, the lattice parameter of Ag nanoparticles was measured as a function of temperature and pressure of hydrogen gas to provide a calibration of the local sample temperature. SAD permits measurement of temperature to ±30 °C using Ag lattice expansion. The method also permits measurement of lattice expansion for nanoparticles that might be difficult to obtain using X-ray methods because of the small volume of material.Citation
