High quality ZnO thin film was grown by Laser MBE. A pure ceramic ZnO target was ablated by the KrF laser pulses (248 nm, 10 Hz, 1 J/cm2) in an ultra high vacuum to deposit ZnO film on sapphire (0001) substrate. The lateral grain size was about 50 nm for the sample with thickness of 55 nm. At room temperature, the pea…
We study theoretically the dependence of absorption by small metallic particles on particle shape and wave polarization in the IR frequency range. We examine the electric and magnetic absorption by small particles. The particles may be either larger or smaller than the electron mean free path. We show that for asymmet…
All articles of this category The Temporary Silicon Connection transforms a potential inter molecular reaction into an intra molecular one, by transiently connecting both partners through a silicon linkage. In addition to entropic advantages, temporary connectivity forces regioselectivity and high stereoselectivity of…
The hydrogen-bond acceptor ability of divalent sulfur in Y —S— Z systems, Y , Z = C, N, O or S, and the donor ability of thiol S—H have been studied using crystallographic data retrieved from the Cambridge Structural Database. Of 1811 Y —S— Z substructures that co-occur with N—H or O—H donors, only 86 (4.75%) form S..…
We resolve a longstanding puzzle for the static and dynamic critical behavior of Gadolinium by a combined theoretical and experimental investigation. It is shown that the spin dynamics of a three dimensional ferromagnet with hcp lattice structure and a spin-spin interaction given by both exchange and dipole-dipole int…
