Learn How AFM Determines Ionic Liquid EDL Structure

(Free download, compliments of Asylum Research, the Technology Leader in atomic force microscopy)

Topics include:

• The advantages and challenges associated with ionic liquid electrolytes
• Ultra-high resolution AFM imaging resolves the ordered structure at the EDL, comparable to results previously only attainable using UHV scanning tunneling microscopy (STM)
• AFM imaging has the added advantage of being in the native state (liquid-solid interface between the ionic liquid and HOPG) instead of frozen for UHV-STM.
• Contact mode AFM force curves also detect ionic liquid ordering at the EDL
• Photothermal excitation (blueDrive) enables even more sensitive detection of ionic liquid ordering using AC-mode (tapping) force curves
