Main Applications of SECM
Electrochemical microscopy

SECM can be used to obtain three-dimensional images of a sample. To do this, the amperometric probe is moved laterally within the plane $(x,y)$ , and changes in the current are measured based on its position above the sample. This mode corresponds to the constant-height regime. The data collected is then converted into a three-dimensional image, with the axis $z$ of the 3D image corresponding to the current $i_{\text{T}}$...
