Choose the correct statement from the following with respect to constant current mode. Correct Answer Feedback electronics adjust height by a voltage

The scanner height in a scanning tunneling microscope, operating in constant current mode, can be adjusted by applying voltage to piezoelectric height control mechanism system. It is a relatively slow method for scanning the sample. Scanner height has to be changed according to the sample topography. When the surface is flat, voltage applied to the z-scanner will reflect variations in local charge density. However, due to atomic step the height of the scanner has to be changed. Image scanned using this instrument contains both topographical and electron density data.
