Electron Energy Loss Spectroscopy was used for the first time to investigate collective properties of metal-containing liquid crystals: the applicability of this experimental technique to investigate electronic properties of liquid crystals is proved. Loss data were collected versus temperature and primary beam energy. Present results show that temperature can change the orientation of molecules with respect to the surface and that the studied material, after few thermal cycles up to 135-degrees-C becomes conductor and keeps its electrical conductivity from the solid state up to the isotropic phase.

Abstract
Electron Energy Loss Spectroscopy was used for the first time to investigate collective properties of metal-containing liquid crystals: the applicability of this experimental technique to investigate electronic properties of liquid crystals is proved. Loss data were collected versus temperature and primary beam energy. Present results show that temperature can change the orientation of molecules with respect to the surface and that the studied material, after few thermal cycles up to 135-degrees-C becomes conductor and keeps its electrical conductivity from the solid state up to the isotropic phase.File in questo prodotto:
