There has been a significant interest on plasmonics in a metallic structure with very narrow gaps for studies of nanophotonics. However, little attention has been paid to the behavior of surface plasmons (SPs) in quasi-continuous metallic structures. This study observes and analyzes intermediate characteristics between propagating SPs (PSPs) and localized SPs (LSPs) in a quasi-continuous metall...

We study the effect of two metallic slabs on collective dynamics electrons in graphene positioned between slabs. show that if are perfect conductors, plasmons display a linear dispersion relation. The velocity these acoustic crucially depends distance metal gates and sheet. In case generic slabs, relation is much more complicated, but we find can still be obtained under specific conditions.

Artificial confinement of electrons by tailoring the layer thickness has turned out to be a powerful tool harness control over competing phases in nano-layers complex oxides. We investigate effect dimensionality on transport properties $d$-electron based heavy-fermion metal CaCu$_{3}$Ru$_{4}$O$_{12}$. Transport behavior evolves from metallic localized regime upon reducing and insulator transiti...

HighNMOSFET structures designed for enhancement mode operation have been fabricated with mobilities exceeding 6000 cm Vs. The NMOSFET structures which have been grown by molecular beam epitaxy on 3-in semi-insulating GaAs substrate comprise a 10 nm strained InGaAs channel layer and a highdielectric layer ( = 20). Electron mobilities of 6000 and 3822 cm Vs have been measured for sheet carrier co...

Iron and magnesium are being considered as promising candidates for biodegradable materials in medical applications, both having their specific advantages challenges. A hybrid of metallic iron a layered composite is studied the present work, to combine merits metals. single-step dip-coating method was employed prepare material. Morphology, composition, crystal structure corrosion behavior Mg/Fe...

To date germanene has only been synthesized on metallic substrates. A metallic substrate is usually detrimental for the two-dimensional Dirac nature of germanene because the important electronic states near the Fermi level of germanene can hybridize with the electronic states of the metallic substrate. Here we report the successful synthesis of germanene on molybdenum disulfide (MoS_{2}), a ban...

We demonstrate a low-cost uncooled terahertz (THz) imager fabricated in a standard 180 nm CMOS process. The imager is composed of a broadband THz metamaterial absorber coupled with a diode microbolometer sensor where the pn junction is used as a temperature sensitive device. The metamaterial absorber array is integrated in the top metallic layers of a six metal layer process allowing for comple...
