Electrical excitation of surface plasmons.
We exploit a plasmon mediated two-step momentum down-conversion scheme to convert low-energy tunneling electrons into propagating photons. Surface plasmon polaritons (SPPs) propagating along an extended gold nanowire are excited on one end by low-energy electron tunneling and are then converted to free-propagating photons at the other end. The separation of excitation and outcoupling proves tha...
متن کاملCarbon Nanotube Transistor Compact Model
In this paper, we describe the development of device models and tools for the design of the carbon nanotube FET (CNFET). Both HSPICE model and Verilog-A model for CNFET including typical device/circuit level non-idealities have been developed. They can be used for design of nanotube transistor circuits as well as to study performance benefits of the new transistor.
متن کاملEfficient unidirectional ridge excitation of surface plasmons.
Using leakage-radiation microscopy, we characterize the efficiency of unidirectional surface-plasmon excitation with periodic (800 nm) arrays of 130-nm-high and 330-nm-wide gold ridges on a thin gold film illuminated with a focused (5-microm-wide) laser beam. We demonstrate that, at the resonant wavelength of 816 nm, the excitation efficiency of > 0.4 can be obtained with >or= 5 ridges by adjus...
متن کاملUnidirectional excitation of surface plasmons by slanted gratings.
Surface plasmon excitation by normally incident light on surface-relief metallic diffraction gratings is studied numerically. Predominantly unidirectional excitation is achieved with a grating of either a slanted lamellar or an inclined sinusoidal groove profile, both having shallow depths. Maps of Poynting vector illustrate that the energy flow turns from normal incidence in the far-field regi...
