Practical Issues on In Situ Heating Experiments in Transmission Electron Microscope

In performing in situ heating transmission electron microscopy (TEM) for materials characterizations, arising concerns such as specimen drifts and unintentional Cu contamination are discussed. In particular, we analysed the thermal and mechanical characteristics of in situ heating holders to estimate thermal drift phenomena. From the experimental results, we suggest an empiri- cal model to describe the thermal drift behavior so that we can design an effective plan for in situ heating experiment. Practical approaches to minimize several hindrances arisen from the experi- ment are proposed. We believe that our experimental recommen- dations will be useful for a microscopist fascinated with the power- ful potential of in situ heating TEM.
