WebOther grain boundaries with high-Σ value or grain boundaries that cannot be described by CSLs, i.e., the misorientation angle of the grain boundary is far beyond the deviations from Brandon’s criterion, are considered as random grain boundaries. This classification proposes a distinction between grain boundaries, which may be susceptible to ...
WebGrain boundaries (GBs) are inevitable defects in large-area MoS 2 samples but they play a key role in their properties, however, the influence of grain misorientation on thermal transport has largely remained unknown. WebGrain Boundaries vs. Texture • Why use the crystal lattice as a frame? Grain boundary structure is closely related to the rotation axis, i.e. the common crystallographic axis between the two grains. • The crystal symmetry applies to both sides of the grain boundary; in order to put the misorientation into the fundamental zone (or
