Grain Boundary Structure and Strength of SiC Bicrystals

Phenomenology and Mechanism of Grain Boundary Sliding in Zinc Bicrystals

Imaging grain boundary grooves in hard-sphere colloidal bicrystals.

Colloidal particles were sedimented onto patterned glass slides to grow three-dimensional bicrystals with a controlled structure. Three types of symmetric tilt grain boundaries between close-packed face-centered-cubic crystals were produced: Σ5(100),Σ17(100), and Σ3(110). The structure of the crystals and their defects were visualized by confocal microscopy, and characterized by simple geometri...

EFFECT OF GRAIN-BOUNDARY STRUCTURE ON STRESS CORROSION CRACKING IN Cu-Al ALLOY BICRYSTALS

CHARGED GRAIN-BOUNDARIES IN n-Ge BICRYSTALS

Germanium bicrystals with two types of low-energy symmetric tilt boundaries, Z 9 and Z 1 1 (CSL model classification) were grown. Current-voltage characteristics of grainboundaries were measured in the temperature range 77 K-420 K. Potential barriers were found only at Z 1 1 boundaries in n Ge which confirms the theoretical predictions of the atomic structure of these boundaries [I]. From the e...

Energetic and spatial distribution of grain boundary states in insb-bicrystals

2014 The spatial and energetic distribution of grain boundary interface states in p-doped InSb-bicrystals with an n-inversion layer adjacent to the grain boundary is determined by fitting the calculated two-dimensional subband structure of the inversion layer to the experimentally obtained data. The total density of inversion electrons ns and the subband occupation nsi are established by magnet...
