The integration of III–V materials on photonic integrated circuits has enjoyed a lot attention because the necessity merging photon sources with silicon electronics. Nevertheless, source technologies are not sufficiently mature, inhibiting employment such platforms to broader range applications. Here, we present novel approach that enables transfer nanolayers (≈250 nm) silicates via oxide bondi...

We investigate the characterization of defect modes in one-dimensional ternary symmetric metallo-dielectric photonic crystal (1DTSMDPC) band-gap structures. We consider the defect modes for symmetric model with respect to the defect layer. We demonstrate reflectance with respect to the wavelength and its dependence on different thicknesses and indices of refraction of dielectric defect layer, a...

TiN/AlTiN ; TiN/CrN and CrN/AlTiN multilayer coatings have been deposited by the cathodic arc evaporation technique. The period is in the range 7 – 200 nm for a total thichness of 3 μm. The period’s control of the nanoscaled hard films is achieved, a priori, by way of a simple geometrical calculation and, a posteriori, via both X-ray diffraction and transmission electron microscopy on cross-sec...

Graphite's lubricating properties due to the "weak" interactions between individual layers have long been known. However, these interactions are not weak enough to allow graphite to readily exfoliate into graphene on a large scale. Separating graphite layers down to a single sheet is an intense area of research as scientists attempt to utilize graphene's superlative properties. The exfoliation ...

A controlled-release formulation of an antihistamine, cetirizine, was synthesized using zinc-layered hydroxide as the host and cetirizine as the guest. The resulting well-ordered nanolayered structure, a cetirizine nanocomposite "CETN," had a basal spacing of 33.9 Å, averaged from six harmonics observed from X-ray diffraction. The guest, cetirizine, was arranged in a horizontal bilayer between ...

Atomically ordered bimetal interfaces typically develop in near-equilibrium epitaxial growth (bottom-up processing) of nanolayered composite films and have been considered responsible for a number of intriguing material properties. Here, we discover that interfaces of such atomic level order can also emerge ubiquitously in large-scale layered nanocomposites fabricated by extreme strain (top dow...

A layered organic-inorganic intercalate was prepared by the self-assembly technique using pamoate (PA) as an organic guest in the Zn-Al layered double hydroxide inorganic host (ZAPAN). Various concentrations of PA, ranging from 0.01 to 0.04 M, were used to prepare the intercalated compound with a constant 4:1 ratio of Zn:Al in the mother liquor. The concentration of PA of 0.02 M at pH 7 was fou...
