A Small Step for Epitaxy, a Large Step Toward Twist Angle Control in 2D Heterostructures
Abstract
<jats:title>Abstract</jats:title><jats:p>2D materials have received a lot of interest over the past decade. Especially van der Waals (vdW) 2D materials, such as transition metal dichalcogenides (TMDCs), and their heterostructures exhibit semiconducting properties that make them highly suitable for novel device applications. Controllable mixing and matching of the 2D materials with different properties and precise control of the in‐plane twist angle in these heterostructures are essential to achieve superior properties and need to be established through large‐scale device fabrication. To gain fundamental insight into the potential control of these twist angles, 2D heterostructures of tungsten disulfide (WS<jats:sub>2</jats:sub>) and graphene (Gr) grown by bottom‐up synthesis via metal‐organic chemical vapor deposition (MOCVD) are investigated using a scanning transmission electron microscope (STEM). Specifically, the combination of conventional high‐resolution imaging with scanning nanobeam diffraction (SNBD) using advanced 4D STEM techniques is used to analyze moiré structures. The latter technique is used to reveal the epitaxial alignment within the WS<jats:sub>2</jats:sub>/Gr heterostructure, showing a direct influence of the underlying Gr layers on the moiré structure in the subsequent WS<jats:sub>2</jats:sub> layers. In particular, the importance of grain boundaries (GBs) within the underlying WS<jats:sub>2</jats:sub> and Gr layers on the structure of moiré patterns with rotation angles below 2° is discussed.</jats:p>
