Publikováno v: Applied Sciences, Vol 9, Iss 23, p 5014 (2019)
Fermi level pinning at metal/semiconductor interfaces forbids a total control over the Schottky barrier height. 2D materials may be an interesting route to circumvent this problem. As they weakly interact with their substrate through Van der Waals fo

Structure and relaxation processes of an anisotropic molecular fluid confined into 1D nanochannels
Autor: Lefort, Ronan, Morineau, Denis, Guégan, Régis, Alain, Moréac, Ecolivet, Claude, Guendouz, Mohammed
Publikováno v: Philosophical Magazine 87, 3-5 (2007) 469-476
Structural order parameters of a smectic liquid crystal confined into the columnar form of porous silicon are studied using neutron scattering and optical spectroscopic techniques. It is shown that both the translational and orientational anisotropic
