accumulative roll bonding (arb) was used to fabricate the cu-zn multilayer and cu-zn solid solution. a lamellar structure with the hardness of about 130 vhn was formed after eight arb cycles. following to the suitable heat treatment, a solid solution with a uniform microstructure and hardness of about 57 vhn was produced. the dominant wear mechanism in the arb processed multilayer was found to ...

X-ray photon beam from a SASE FEL undulator is in principle a single user tool, just like an optical laser. Therefore, the operation and amortization cost cannot be easily spread over many simultaneous experiments. To avoid prohibitive cost for each experiment, a new XFEL laboratory scheme is proposed. The wavelength range 0.1-1.6 nm at fixed electron energy of 15 GeV can be covered by operatin...

Abstract Monolayers of hexagonal boron nitride (hBN) are grown on graphite substrates using high-temperature molecular beam epitaxy (HT-MBE). The hBN monolayers observed to grow predominantly from step edges the surface and exhibit a strong dependence morphology, including dominant crystallographic edge, monolayers, growth temperature, as well systematic variations in rate coverage, significant...

Multilayer metal-ceramic films have the potential to serve as strong, tough and environmentally resistant films and coatings for a wide variety of applications. They derive their properties from the multilayer structure (architecture), the microstructure and, hence, mechanical properties of the individual layers and the stress state of the film. However, in order to realize the potential of mic...

Multilayer networks are a useful way to capture and model multiple, binary relationships among a fixed group of objects. While community detection has proven to be a useful exploratory technique for the analysis of single-layer networks, the development of community detection methods for multilayer networks is still in its infancy. We propose and investigate a procedure, called Multilayer Extra...

A centrosymmetric multilayer stack of two transparent thin-film materials, which is embedded in a high-index prism, is designed to function as an efficient polarizer or polarizing beam splitter (PBS) under conditions of frustrated total internal reflection over an extended range of incidence angles. The S(LH)(k)LHL(HL)(k)S multilayer structure consists of a high-index center layer H sandwiched ...

Epitaxial thin film growth by vapor deposition or molecular beam epitaxy under ultra‐high vacuum conditions generally occurs in two stages: (i) nucleation and growth of well‐separated islands on the substrate; (ii) subsequent formation of a thicker continuous film with possible kinetic roughening. For homoepitaxial growth, two‐dimensional (2D) monolayer islands are formed during submonolayer de...

We experimentally observe the “superprism effect” in a periodic thin-film structure acting as a one-dimensional photonic crystal. The design of non-periodic structures exhibiting a linear shift with wavelength in the EDFA C-band is discussed. 2002 Optical Society of America OCIS codes: (260.2030) Dispersion; (060.4230) Multiplexing; (230.4170) Multilayers WDM systems create a strong need for c...
