| Abstract: | Combined scanning tunneling and atomic force microscopy (STM/AFM) of cross-sectional cleavages in a protective liquid medium (oil) is applied to study InGaAs/GaAs heterostructures with quantum wells and dots. It is shown that the quantum wells and dots can be visualized on cleavages in both AFM and STM modes and to measure the current-voltage characteristics of the contact between an AFM probe and the cleavage surface. |
