Although the sub-angstrom resolution of the modern transmission electron microscope (TEM) has made major contributions to defect structure analysis in many fields (such as oxides, interfaces, nanoparticles and superconductors) it has yielded little direct information on the core structure of dislocations. We suggest that “forbidden reflection” lattice images recorded in an ultra-high vacuum TEM in projections normal to the dislocation line could provide interpretable images of cores at atomic… 
Strain fields around dislocation arrays in a Σ9 silicon bicrystal measured by scanning transmission electron microscopy
Strain fields around grain boundary dislocations are measured by applying geometric phase analysis on atomic resolution images obtained from multiple fast acquisitions in scanning transmission
Imaging screw dislocations at atomic resolution by aberration-corrected electron optical sectioning
It is shown that screw displacements can be imaged directly with the dislocation lying in a plane transverse to the electron beam by optical sectioning using annular dark field imaging in a scanning transmission electron microscope, thereby demonstrating a new method for characterizing dislocation core structures.
Temperature evolution of defects and atomic ordering in Si1−xGex islands on Si(001)
The observation of atomic ordering and signatures of defects in self-assembled Ge islands using x-ray diffraction techniques have been previously treated as unrelated subjects. However, mutual
In Situ Transmission Electron Microscopy
This chapter aims to demonstrate how in situ microscopy has enhanced the understanding of dynamic phenomena associated with phase transformations, catalysis, crystal growth, liquid-phase processes, electrical and mechanical properties, magnetism, and ferroelectricity.
Nano-Particle TEM Sample Preparation Primer
As nanotechnology continues to drive scientific research, it becomes increasingly difficult to characterize the “nano” structures. Transmission electron microscopy (TEM) has proven to be a
Low-temperature intrinsic plasticity in silicon at small scales
Direct Observation of a Screw Dislocation Normal to the Beam by Z‐Contrast STEM
Dislocation core structures in metals and ceramics are long-standing questions in materials research. Detailed knowledge about core structure of screw dislocations remains a major challenge. We have


Forbidden-reflection lattice imaging for the determination of kink densities on partial dislocations
Abstract High-resolution electron microscope lattice images have been obtained at the Schemer focus setting for the first time from the ′forbidden′ {422}/3 Bragg reflections which result from
Determination of core structure periodicity and point defect density along dislocations
Understanding the structure of defects in crystalline materials is essential for modern materials science. While most defect characterization involves the inverse and non-unique problem of fitting
Modelling of HREM and nanodiffraction for dislocation kinks and core reconstruction
The ability to directly image individual dislocation kinks (Kolar H et al 1996 Phys. Rev. Lett. 77 4031) opens up many possibilities for the study of kink dynamics by in situ TEM. Unfortunately, this
Electronic and atomic structure of a dissociated dislocation in SrTiO3
A [001](110) small-angle grain boundary SrTiO 3 was studied by electron-energy-loss spectroscopy (EELS) and high-resolution transmission electron microscopy. The a grain boundary dislocations were
The Structure And Electrical Properties Of Dislocations In Semiconductors
Evidence from weak beam electron microscopy shows that dislocations introduced by deformation of crystals of tetrahedrally coordinated semi‐conductors are dissociated into partials, and suggests that
Direct observation of the shear APB interface in Fe3Al by HREM
Abstract Atomic arrangements at a nearest neighbour anti-phase boundary (APB), on the (110) plane, connected by 1/2[111] superpartials in Fe3Al were directly observed in an edge-on view using high
Observation of Moving Dislocation Kinks and Unpinning.
Atomic resolution electron microscopy has been used to obtain images of moving dislocation kinks on partial dislocations at 600 ±C in silicon and kink formation energy is obtained from the distribution of kink pair separations in low-dose images and is compared to the kink migration energy.
Kinks on Partials of 60° Dislocations in Silicon as Revealed by a Novel TEM Technique
The stacking fault ribbon of dissociated 60 dislocations in silicon is imaged with resolution better than 0.33 nm. The dissociation width of the dislocations had been frozen in under high shear

Abstract The motion of single dissociated dislocations in germanium and silicon has been studied directly in the electron microscope by moans of the weak-beam technique and utilizing a heating stage.
Dislocation motion in strained thin films. Are Kinks colliding with each other
For epi-threading dislocations in Si0.9Ge0.1 strained epitaxial films grown on Si, the velocity of their lateral propagation parallel to the hetero-interface is found to increase almost linearly with
