“…With an enhanced cooling design using argon flow for nucleation, we also observed similar results [16]. Therefore, this concept using dendrite casting for getting a high percentage of high symmetry grain boundaries, such as coincidence site lattice (CSL) boundaries and twins at the nucleation stage is getting recognized [4,6,15,16]. Because silicon is a highly anisotropic material, its growth habit is strongly affected by undercooling [17,18].…”
