STM/STS Study of the Density of States and Contrast Behavior at the Boundary between (7 × 7)_N and (8 × 8) Structures in the SiN/Si(111) System

Crystals, 2022
The origin of the contrast appearing in STM images at the boundary between diverse ordered structures is studied using the example of two structures, (7 × 7)N and (8 × 8), formed in the system of a two-dimensional silicon nitride layer on the Si(111 ...
