Summary
Folds in few-layer graphene (FLG) grown by chemical vapor deposition (CVD) create stacking faults near the crease. These structural changes impact electronic properties, crucial for device fabrication.
Area of Science:
- Materials Science
- Condensed Matter Physics
- Nanotechnology
Background:
- Graphene grown by chemical vapor deposition (CVD) often exhibits folds and creases.
- These defects arise from differences in thermal expansion between graphene and its catalyst, and during transfer processes.
Purpose of the Study:
- To investigate the atomic structure of creases in few-layer graphene (FLG).
- To understand how these creases affect the crystal stacking and electronic properties of FLG.
Main Methods:
- Aberration-corrected high-resolution transmission electron microscopy (AC-HRTEM) was employed.
- 2D Fast Fourier Transforms (FFTs) and real-space image analysis were used to elucidate crystal structure.
- Multislice atomistic transmission electron microscopy (TEM) simulations corroborated the findings.
Main Results:
- Strain-induced stacking faults were identified in the AB Bernal-stacked FLG near crease terminations.
- The detailed layer configuration within the crease was determined.
- Significant out-of-plane distortions were observed at crease termination points.
Conclusions:
- The formation of stacking faults in FLG creases due to strain is confirmed.
- Understanding these structural modifications is essential for predicting and controlling the electronic properties of transferred CVD-graphene.
- These findings are critical for the successful fabrication of electronic devices using FLG.

02:11Conformations of Cyclohexane
Cyclohexane does not exist in a planar form due to the high angle and torsional strain it would experience in the planar structure. Instead, it adopts non-planar chair and boat conformations.
The chair form is the most stable and derives its name from its resemblance to the “easy chair.” In the chair conformation, two carbon atoms are arranged out-of-plane — one above and one below, minimizing the torsional strain. In the chair form, the bond angle is very close to the ideal tetrahedral value,...

01:25Imperfections 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...
01:18Deformations in a Symmetric Member in Bending
When analyzing the deformation of a symmetric prismatic member subjected to bending by equal and opposite couples, it becomes clear that as the member bends, the originally straight lines on its wider faces curve into circular arcs, with a constant radius centered at a point known as Point C. This phenomenon helps to understand the stress and strain distribution within the member more clearly.
When the member is segmented into tiny cubic elements, it is observed that the primary stress...

02:29Conformations of Cycloalkanes
Adolf von Baeyer attempted to explain the instabilities of small and large cycloalkane rings using the concept of angle strain — the strain caused by the deviation of bond angles from the ideal 109.5° tetrahedral value for sp3 hybridized carbons. However, while cyclopropane and cyclobutane are strained, as expected from their highly compressed bond angles, cyclopentane is more strained than predicted, and cyclohexane is virtually strain-free. Hence, Baeyer’s theory that was based on the...
01:21Deformations in a Transverse Cross Section
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...

01:26Imperfections in Crystal Structure: Stoichiometric Point Defects
Schottky defects arise when some lattice points in a crystal, such as those in NaCl, remain unoccupied, creating lattice vacancies without disturbing the overall electrical neutrality of the crystal. This defect is common in ionic crystals where the positive and negative ions are similar in size, as seen in sodium chloride and cesium chloride. The presence of Schottky defects enables the crystal to conduct electricity to a small extent through an ionic mechanism. Electric fields cause nearby...
