WebMar 14, 2024 · As mentioned in Section 2, the preferred condition for ensuring epitaxial growth is higher thermal gradient G and lower solidification rate V. Thus, aside from the managing laser scanning direction to coordinate with substrate crystallographic orientation, applying extra cooling on the substrate seems viable for promoting epitaxial grain growth ... WebSep 21, 2024 · This alignment is referred to as lattice preferred orientation or crystallographic preferred orientation (CPO). When the shear strain causes strong alignment over a large enough volume, the CPO creates an observable anisotropy in seismic observations made at stations on the Earth's surface.
