Previous papers have described the theory (1-3) and ap-plications (4-12) of the scanning
electrochemical microscope (SECM) operating in the steady-state current regime. The tip …

The steady-state current that flows between the scanning tip (a disk ultramicroelectrode
Imbedded In an Insulating sheath) and a planar sample substrate In a scanning …

We discuss SECM tip voltammetry, where a UME tip is held above a conductive substrate
within about a tip radius and a tip voltammogram is recorded as its potential is slowly …

Theory for the problem, relating the SECM feedbackcurrent to the tip-substrate distance, tip
electrode radius, and rate constant for the chemical step, is developed numerically by …

An approximate theory for the feedback mode of the scanning electrochemical microscope
(SECM) is developed to interpret the effects of substrate shielding on an ultramicroelectrode …

The technique of scanningelectrochemical microscopy (SECM) Is described. In this
technique the electrolysis current that flows as an ultramicroelectrode tip (diameter ca. 10 …

The dependence of the SECM feedback current on finite heterogeneous electron-transfer
(et) kinetics at the substrate electrode was examined by experimental studies of the redu …

INTRODUCTION In scanning electrochemical microscopy (SECM), a micro-voltammetric tip
electrode (eg, microdisk geometry with a tip radius of the order of micrometers) is rastered in …

The dependence of the SECM feedback current on finite heterogeneous electron-transfer

In this paper we describe tip-position modulationscanning electrochemical microscopy (TPM
SECM), a new mode of operation of the scanning electrochemical microscope (SECM) …
