Ce. Bach et al., EFFECTIVE INSULATION OF SCANNING-TUNNELING-MICROSCOPY TIPS FOR ELECTROCHEMICAL STUDIES USING AN ELECTROPAINTING METHOD, Journal of the Electrochemical Society, 140(5), 1993, pp. 1281-1284
We report here on a new, straightforward, and effective method for ins
ulating etched and cut Pt/Ir scanning tunneling microscopy (STM) tips
for in situ electrochemical studies. The coating was formed by electro
phoretic painting and subsequent heating. It covered all but the very
end of the tip, which may be attributed to shrinking of the polymer du
ring heating. We have characterized these tips by voltammetric methods
, scanning electron microscopy, and by in situ STM imaging.
