摘要: The properties of the nematic-isotropic interface nematic liquid crystal 7CB are studied by optical reflectometry. It is found that at director tilted with respect to vertical axis. Measurements reported tilt angle θν thickness interface, and anchoring energy Etude par reflectometrie optique des proprietes de l'interface nematique-isotrope. Mesure l'epaisseur l'interface, l'angle polaire du directeur a et son energie d'ancrage
