Tip‐bias induced surface modification on gold surfaces

Abstract

We have observed drastic modification of gold surfaces at tip biases above a threshold value. These modifications were observed only on surfaces which are not atomically flat and only with negative tip bias. We tentatively attribute these surface modifications to formation of Taylor cones.

“…Au surfaces after operation at high current and/or bias to melting [54,55]. Nagahara et a1 reported that increasing the tip bias beyond -1.4 V caused rough areas on a Au sample to blister and become unstable [54]. They were unable to cause the same effect on smooth gold surfaces for biases as large as 2.5 V. Platinum (which has a higher melting point) did not exhibit blistering on either rough or smooth surfaces.…”
