Core reconstruction of the 90-degree partial dislocation in non-polar semiconductors
R. W. Nunes, J. Bennetto, David Vanderbilt
We investigate the energetics of the single-period and double-period core reconstructions of the 90-degree partial dislocation in the homopolar semiconductors C, Si, and Ge. The do…

Atomic structure of dislocation kinks in silicon
R. W. Nunes, J. Bennetto, David Vanderbilt
We investigate the physics of the core reconstruction and associated structural excitations (reconstruction defects and kinks) of dislocations in silicon, using a linear-scaling de…

A period-doubled structure for the 90-degree partial dislocation in silicon
J. Bennetto, R. W. Nunes, David Vanderbilt
We suggest that the commonly-accepted core structure of the 90-degree partial dislocation in Si may not be correct, and propose instead a period-doubled structure. We present LDA,…
