By using different combinations of far-field alignment and mesogen dielectric anisotropy, we unravel the nature and stability of point defects and disclinations resulting from the hybrid boundary conditions.7 p.application/pdfeng(c) American Physical Society, 2014Cristalls líquidsQuímica de superfíciesAgents tensioactiusLiquid crystalsSurface chemistrySurface active agentsinfo:eu-repo/semantics/article6438202019-02-01info:eu-repo/semantics/openAccess
