Extended Data Fig. 3: Dislocation characteristics of intrinsic SF, extrinsic SF, and ITB with configuration I.
From: Structural transition and migration of incoherent twin boundary in diamond
a, An intrinsic SF bordered by a 30° mixed partial dislocation \((1/6[2\bar{1}\bar{1}])\). b, An intrinsic SF bordered by a 90° pure edge partial dislocation \((1/6[\bar{1}2\bar{1}])\). c, An extrinsic SF bordered by a partial-doublet containing one 30° mixed partial dislocation \((1/6[2\bar{1}\bar{1}])\) and one 90° pure edge partial dislocation \((1/6[\bar{1}2\bar{1}])\). d, An ITB with the configuration I, exhibits a partial triplet containing two 30° mixed partial dislocations (\(1/6[2\bar{1}\bar{1}]\) and \(1/6[\bar{1}\bar{1}2]\)) and one 90° pure edge partial dislocation \((1/6[2\bar{1}\bar{1}])\). e, The Burgers vectors of these partial dislocations. f, The structural models of these SFs and ITB corresponding to a to d, respectively. g,h, EELS line-scan across an ITB performed at an accelerating voltage of 200 kV, confirming the presence of sp2 bonds.
