Cadmium selenide nanowires in the wurtzite bulk phase, connected to gold electrodes are studied using local density approximation. The short wire is fully metalized by metal-induced gap states. For longer wires, a gap similar to that in bare cadmium selenide nanowires is observed near the center while sub-gap structure emerges near the metal-semiconductor nanocontact. This behavior is attribute...

Integration of planar circuits to non-planar ones has been recently considered as a credible technique for low-cost mass production of microwave and millimeter-wave circuits and systems. This paper regards these concepts that provide for a complete integration of planar circuits and waveguide filters synthesized on a single substrate by means of metalized post (via-hole) arrays. A method of des...

Inspired by nature's ability to fabricate supramolecular nanostructures from the bottom-up, materials scientist have become increasingly interested in the use of biomolecules like DNA, peptides, or proteins as templates for the creation of novel nanostructures and nanomaterials. Although the advantages of self-assembling biomolecular structures clearly lie in their chemical diversity, spatial c...

Understanding the Verwey transition in magnetite (Fe3O4), a strongly correlated magnetic oxide, is one-century-old topic that recaptures great attention because of recent spectroscopy studies revealing its orbital details. Here, modulation by tuning configurations with ionic gating reported. In epitaxial thin films, insulating state can be tuned continuously to metallic showing low-temperature ...
