| Abstract: | The Mo(1 1 2) and Mo(1 1 1) surfaces have been studied by STM and DFT/GGA modeling. Due to high quality and cleanness of the surfaces, for the first time good STM images of large fragments of the Mo(1 1 2) and Mo(1 1 1) have been obtained. Lack of atomic resolution in the rows of the Mo(1 1 2) surface is attributed to flatness of distribution of density of the electronic states along the rows. This suggestion is illustrated by comparison of STM images for Mo(1 1 1) and Mo(1 1 2) and model calculations of STM pictures for these surfaces. |
