Abstract
The first two-dimensional scanning tunneling microscope (STM) measurements on cleaved shallow silicon p-n junctions are presented. The current imaging technique provides contrast between p- and n-type regions on biased junctions. The two-dimensional part of the junction is imaged and localized to within 30 nm. Both the cleaving of the junction and the STM measurements are performed in ultrahigh vacuum (UHV).<>
