K. Ozeki et al., Visualizing the interrelation between surface topograph and surface potential by means of a scanning Maxwell stress microscope, JPN J A P 1, 39(9A), 2000, pp. 5261-5262
An scanning Maxwell stress microscope (SMM) is utilized to visualize, on a
microscale, the intercorrelation between the surface topograph and correspo
nding surface potential. It is found that the surface potential of the Fe-4
2Ni sample surface is weakly negatively correlated with the topographic hei
ght, while there is no correlation in the case of the Au surface used as a
reference.
