Anisotropic excitonic effects in the energy loss function of hexagonal boron nitride

S. Galambosi, L. Wirtz, J.A. Soininen, J. Serrano, A. Marini, K. Watanabe, T. Taniguchi, S. Huotari, A. Rubio, K. Hamalainen

The anisotropy of the valence energy-loss function of hexagonal boron nitride (hBN) is shown to be largely enhanced by the highly inhomogeneous character of the excitonic states. The energy loss with momentum transfer parallel to the BN layers is dominated by strongly bound, quasi-two-dimensional…

Band gap engineering in simultaneous phononic and photonic crystal slabs

Bahram Djafari-Rouhani, Yan Pennec, El Houssaine El Boudouti, Jerome O. Vasseur, Youssef El Hassouani, C. Li, Abdellatif Akjouj, Driss Bria

We discuss the simultaneous existence of phononic and photonic band gaps in two types of phononic crystals slabs, namely periodic arrays of nanoholes in a Si membrane and of Si nanodots on a SiO2 membrane. In the former geometry, we investigate in detail both the boron nitride lattice and the…

Mechanical characterization of aluminium nanofilms

Gregory Guisbiers, Etienne Herth, L. Buchaillot

The mechanical properties (Young’s modulus, hardness, wear resistance) of aluminium nanofilms on silicon substrate are studied. Size effect on these mechanical properties are exhibited. Young’s modulus, hardness and wear resistance increases when the thickness is reduced. Experimental…
