DOI: 10.1002/advs.202515752

Abstract: Surface alignment and edge dislocations are explored in the recently discovered twist-bend ferroelectric nematic, NTBF, in which the vector of spontaneous polarization follows an oblique helicoidal trajectory around a polar twist-bend axis. In a planar… read more here.

DOI: 10.1016/j.commatsci.2016.11.038

Abstract: Abstract The impingement of edge dislocations on nano-scale interfaces formed when bringing in contact aluminum crystals is investigated using molecular dynamics simulations. Dislocations, inserted in the bottom crystal, glide towards the contact when the two… read more here.

DOI: 10.1016/j.jmps.2017.04.018

Abstract: Abstract Continuum theory of dislocation aims to describe the behavior of large ensembles of dislocations. This task is far from completion, and, most likely, does not have a “universal solution”, which is applicable to any… read more here.

DOI: 10.1039/d3sm01516e

Abstract: The interaction between two edge dislocations in a sheared lyotropic lamellar liquid-crystalline medium is examined. The model is a mesoscale hydrodynamic model based on a free-energy functional that is minimised for a sinusoidal concentration modulation… read more here.

DOI: 10.1063/1.5034198

Abstract: Computational analysis via molecular dynamics and density functional theory simulations elucidated the structural and electronic properties of a-type basal edge dislocations lying in the ⟨1–100⟩ direction in wurtzite GaN. As a particular and predominant type… read more here.

DOI: 10.3390/ma18235453

Abstract: Dislocations in third-generation semiconductor gallium nitride (GaN) have always been a subject of intense study. Here, we investigate the core structures and electronic properties of prismatic edge dislocations in wurtzite GaN using a combination of… read more here.
