Abstract
A new method is introduced to study transport in a mesoscopic sample. The electric field from an STM-tip is used to locally influence a meso scopic object. We detect abrupt changes in the mesoscopic signal both as a function of the tip position and tip-sample voltage. They could b e interpreted as due to spatial shifts or changes in the activity of s cattering centers in the sample.
