Abstract

The STM images of NaCl microcrystal at room temperature have been studied in the air. The results show that the ionic conductivity plays a crucial role in the image formation. The resolution of the microcrystals is restricted due to surface condensation of water molecules on the sample, and the phenomenon of "dragging effect" appears on the NaCl images. The effects of bias voltage and humidity to the tunneling process are also discussed.
