➀ Stanford University scientists have used a specialized electron microscope to explore the microstructure of promising soft semiconductors. The research focuses on organic mixed ionic-electronic conductors (OMIECs) with potential applications in next-generation batteries and electronics. The study reveals the internal structure and electron transport mechanisms of OMIECs. ➁ The research technique, cryo 4D-STEM, allows for the observation of the material's microstructure in action, providing insights into how the material performs under stress. ➂ The findings could have significant implications for future research on OMIEC polymers and their electronic applications.
