AFM Modes

Scanning Electrochemical Potential Microscopy (SECPM)

The resolution of STM in a dynamic chemical environment

Probing the nanoelectrical characteristics of a substance as an electrochemical reaction takes place can be of interest in a variety of research fields, such as biochemistry, corrosion, and battery development. Both SECPM and Electrochemical AFM (EC-AFM) techniques are used to investigate electrochemical changes at electrode/electrolyte interfaces. SECPM detects and images potential changes across the sample surface, while EC-AFM detects electrostatic forces.

SECPM provides insights into electrochemical reactions at the liquid/sample interface by mapping the potential distribution of the surface with a resolution comparable to Scanning Tunneling Microscopy (STM).
