In situ transmission electron microscopy of resistive switching devices (B09)

• Subject Area: Experimental Condensed Matter Physics
• Term: from 2015 to 2023
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 167917811

In Project B9, the focus will be on in situ TEM characterization of novel PCM and VCM materials during switching processes. Changes in atomic structure and local electric field distributions will be tracked with sub-nm spatial resolution using both pixelated STEM techniques and off-axis electron holography. For PCMs, the primary focus will be on studies of spatially confined devices, for which the small device sizes and short retention times complicate imaging. For VCMs, the primary focus will be on studies of defects, which require sub-atomic-resolution structural and chemical analysis.
