The motion of line defects (dislocations) has been studied for more than 60 years, but the
maximum speed at which they can move is unresolved. Recent models and atomistic …

It is well known that diamond does not deform plastically at room temperature and usually
fails in catastrophic brittle fracture. Here, we demonstrate room-temperature dislocation …

It is thought that dislocations cannot surpass the sound barrier at the shear wave velocity
because the energy spent in radiation has a singularity there. Atomistic simulations show …

The dissociation of 60 and screw dislocations in diamond is modeled in an approach
combining isotropic elasticity theory with ab initio–based tight-binding total-energy …

The core structure and stability of the 90 partial dislocation in diamond is studied within
isotropic elasticity theory and ab initio total energy calculations. The double-period …

We review first-principles calculations of dislocation core structure in diamond, and draw out
similarities with and differences from silicon. Primary differences are in hybridization …

Individual dislocations in high-pressure high-temperature-grown single-crystal diamond with
a dislocation density of less than 47 cm− 2 in the (001) growth sector were observed using …

From studies of anisotropy in Knoop hardness1 and transmission electron microscopy of the
deformation beneath indentations2, it is widely accepted that some dislocation movement is …

The structures and core energies of dislocations in diamond are calculated using both
isotropic and anisotropic elasticity theory combined with ab initio–based tight-binding total …

Dislocations are common defects in both natural as well as in CVD‐grown diamond. Recent
advances in the growth of high quality single crystal CVD diamond have led to an increased …
