In this paper, the surface potential and the space charge generated during the first stages of atomic force microscopy field-induced oxidation were measured and shown to be an intrinsic feature in local oxidation experiments.Abstract:
We have measured the surface potential and the space charge generated during the first stages of atomic force microscopy field-induced oxidation. Space charge densities are about 1017 cm−3 for oxidation times below 10 ms. In a dry atmosphere, the surface potential is negative. However, in humid air the surface potential could be either positive or negative. This effect is attributed to a screening effect of the water molecules. These results explain and support the use of local oxidation patterns as templates for building molecular architectures. They also establish the space charge build up as an intrinsic feature in local oxidation experiments.read more

TL;DR: In this article, the authors reported the results of atomic force microscopy local anodic oxidation experiments on 6H-SiC in air and found that the diminished density and the change in chemical composition of the oxide grown on SiC with respect to oxide grown under similar condition on Si caused a drop in the activation energy of oxanions diffusion within the newly formed oxide layer.
