Strain, composition and disorder in ADF imaging of semiconductors

Strain, composition and disorder in ADF imaging of semi- conductors

The effect of strain, composition and disorder in ADF images is systematically studied as a function of detection angle in order to understand the main contrast mechanisms. We demonstrate that the complex phenomenology in ADF images can be accounted for by accurate simulations and modelling. The advantage of an accurate modelling on the image interpretation will be demonstrated in the case of d...

Atomic Imaging Across Strain Boundaries in Bilayer Graphene with ADF-STEM and DF-TEM

Bilayer graphene possesses two degenerate lowest energy configurations which are geometrically mirrored—AB and BA stacking[1]. Both stacking geometries have been observed as domains in bilayer systems grown by chemical vapor deposition[2]. Here we examine the structure at the interfaces of stacking domains using atomic-resolution scanning transmission electron microscopy (STEM) and standard dar...
