Defect modes caused by twinning in one-dimensional photonic crystals
with a twin defect is studied using a transfer-matrix method. We derive analytical expressions for the frequency of defect modes and for the enhancement of the electromagnetic field inside the defect. In particula...

Time-domain terahertz study of defect formation in one-dimensional photonic crystals
One-dimensional photonic crystals composed of silicon and air layers with and without twinning defect are studied by means of terahertz time-domain transmission and reflection spectroscopy. It is shown and experimentally demonstrate...

Characterization of the matrix-twin interface of a (1 0 -1 2) twin during growth
A model of twin growth in magnesium is presented together with the analysis of defects responsible for this growth. The twin interface is represented by {10-12 dipoles superimposed on basal-prismatic and conjugate twin<...

Slip dislocation and twin nucleation mechanisms in hcp metals
A new nucleation mechanism is proposed for {10 1 - 1} deformation twin in hcp is about 7 % of shear modulus), the core of a slip dislocation can transform to a twin embryo. The transformation and subsequent twin growth are ...

Non-diffusional growth mechanism of I-1 basal stacking-faults inside twins in hcp metals
Deformation twins in magnesium exhibit considerable densities of I-1 basal-plane stacking-faults. Since these faults generally transect their host twin, they presumably lengthen concommitantly with boundary migration during twin...

Real-time atomic-resolution observation of coherent twin boundary migration in CrN
microscopy, we report two different twin boundary defect (TD) nucleation and CTB migration modes at the CTB/ITB (incoherent twin boundary) and CTB/surface junctions. A new twin defect nucleation and CTB m...

Planar defects on {121} plane in 2H structure
The structures of stacking faults and twin boundaries on {121} plane in 2H structure are modelled by using of many-body potentials. Two types of stacking faults and three types of twin boundaries were found as result of calculation....

Unravelling the nucleation and growth of {11-(2)over-bar2} twins
competing structures of twin boundary. The twin growth is mediated by subsequent glide of step-like defects (disconnections) along the {1122} boundary. The twin shearA recently proposed mechanism of {11 <(2) over ...
