edge dislocation

edge dislocation

[′ej ‚dis·lō‚kā·shən]
(crystallography)
A dislocation which may be regarded as the result of inserting an extra plane of atoms, terminating along the line of the dislocation. Also known as Taylor-Orowan dislocation.

The edge dislocation was first proposed by Orowan [27], Polanyi [28] and Taylor [29] in 1934, while the screw dislocation was proposed by Burgers [30] in 1939.

We consider a stationary edge dislocation in the spacetime continuum in cartesian coordinates (x; y; z), with the dislocation line along the z-axis and the Burgers vector [b.
The high tensile load produces plastic flow due to movement of edge dislocation with Cottrell atmosphere such that the edge dislocation separates from the enclosed interstitial solutes.
Some paper subjects are defect analysis in semiconductor materials based on p-n junction diode characteristics, electronic structure and doping effects of Ni and Co on a kink in the edge dislocation of BCC iron, peculiarities of discontinuous precipitation in the Pb-Sn alloy, and local vibrational modes of Zn-H-P in GaP, InP, and ZnTe.
The binding energy of a boron atom to an edge dislocation is considered to be large (~0.
4) The first peak is due to a frictional drag of boron atoms on mobile dislocations, including the interaction between boron atoms and mobile edge dislocations as shown in a solute atmosphere model.
More complex is instead the interaction with the dislocation; thinking for simplicity one edge dislocation, for instance, the local lattice distortion due to stress field of the extra-plane affects the path of the ions between the electrodes depending on the orientation of the Burgers vector with respect to the applied electric field.
actually inferred in [9]: the interaction of the charge carrier with the stress field of one edge dislocation defines an effective diffusion coefficient [D.
In the case of edge dislocation the shear stress component on a plane at distance [gamma] above the slip plane is known to be [[sigma].
There are two types of dislocations [1]: 1) Edge dislocations corresponding to dilatations, longitudinal displacements with an associated rest-mass energy, are identified with particles, and 2) screw dislocations corresponding to distortions, transverse displacements which are massless, are identified with photons.
