Imperfections in Crystal Structure: Point, Line and Plane Defects

Imperfections in Crystal Structure: Point, Line and Plane Defects

A perfect crystal, in theory, has a uniform structure with the same unit cell and lattice points throughout. However, any deviation from this periodic arrangement is known as an imperfection or defect. These defects can be categorized into three types: point, line, and plane defects.Point defects occur when there is a deviation from the ideal due to missing atoms, displaced atoms, or additional atoms. These imperfections might occur due to imperfect packing during crystallization or because of...

Background:

van der Waals (vdW) crystals exhibit weak interlayer interactions, leading to structural instability like twisting and buckling.
Controlled synthesis of stacking-fault-free vdW multilayers is crucial for applications, especially as ultrathin semiconducting channels.

Purpose of the Study:

To achieve deterministic epitaxial growth of single-crystalline hexagonal bilayer molybdenum disulfide (MoS₂).
To enhance the structural robustness and interlayer coupling of multilayer vdW crystals.

Main Methods:

Layer-by-layer deposition incorporating molybdenum (Mo) interstitials between MoS₂ layers.
Atomic-resolution analysis to characterize interstitial site and bonding.
Density functional theory (DFT) calculations to understand nucleation and phase selectivity.

Main Results:

Successfully grew single-crystalline hexagonal bilayer MoS₂ with incorporated Mo interstitials.
Achieved exceptional structural robustness, preventing interlayer rotational and translational misalignments.
Mo interstitials anchor interlayer registry via tetrahedral bonding with sulfur atoms.

Conclusions:

Mo interstitials effectively stabilize multilayer vdW crystal growth.
This method enables deterministic synthesis of stacking-fault-free multilayers with controlled stacking order.
The approach enhances interlayer coupling for improved material properties.
