We demonstrate the fabrication of the large-area arrays of vertically aligned Si/SiO2 nanowires with full tunability of the geometry of the single nanowires by the metal-assisted chemical etching technique and the following thermal oxidation process. To fabricate the geometry controllable Si/SiO2 nanowire (NW) arrays, two critical issues relating with the(More)
The organic monolayer colloidal crystals, which are usually prepared by self-assembling, could be used as templates, due to their interstitial geometry, for the periodically arranged nanostructured arrays, which have important applications in many fields, such as photonic crystals, information storage, super-hydrophobicity, biological and chemical sensing.(More)
—Security of heterogeneous wireless network is the research hotspot now. Aiming at the security problems of access authentication for heterogeneous wireless network, an access authentication scheme based on CPK technology is presented. The access authentication model is based on CPK technology to realize identity authentication, temporary authentication(More)
QoS-Based Services Selecting and Optimizing Composition between the peers play an increasingly important role to ensure interop-erability on Grid environment. However, the prohibitive cost of selecting , matching, mapping and composing algorithm has now become a key bottleneck hindering the deployment of a wide variety of Grid services. In this paper, we(More)
