Absorption of light in a single vertical nanowire and a nanowire array

Vertical Nanowire Array-Based Light Emitting Diodes

Address correspondence to [email protected] ABSTRACT Electroluminescence from a nanowire array-based light emitting diode is reported. The junction consists of a p-type GaN thin fi lm grown by metal organic chemical vapor deposition (MOCVD) and a vertical n-type ZnO nanowire array grown epitaxially from the thin fi lm through a simple low temperature solution method. The fabricated devices ex...

Plasmon-Enhanced Light Absorption in GaAs Nanowire Array Solar Cells

In this paper, we propose a plasmon-enhanced solar cell structure based on a GaAs nanowire array decorated with metal nanoparticles. The results show that by engineering the metallic nanoparticles, localized surface plasmon could be excited, which can concentrate the incident light and propagate the energy to nanowires. The surface plasmon can dramatically enhance the absorbance of near-bandgap...

Absorption of light in a single-nanowire silicon solar cell decorated with an octahedral silver nanocrystal.

In recent photovoltaic research, nanomaterials have offered two new approaches for trapping light within solar cells to increase their absorption: nanostructuring the absorbing semiconductor and using metallic nanostructures to couple light into the absorbing layer. This work combines these two approaches by decorating a single-nanowire silicon solar cell with an octahedral silver nanocrystal. ...

Superconducting-nanowire single-photon-detector linear array

Phonon spectroscopy in a Bi2Te3 nanowire array.

The lattice dynamics in an array of 56 nm diameter Bi2Te3 nanowires embedded in a self-ordered amorphous alumina membrane were investigated microscopically using (125)Te nuclear inelastic scattering. The element specific density of phonon states is measured on nanowires in two perpendicular orientations and the speed of sound is extracted. Combined high energy synchrotron radiation diffraction ...
