Vertical nanowire arrays were prepared from an organic dye compound, 1,5-diaminoanthraquinone (DAAQ), on various types of substrates by a facile physical vapor transport method. It was found that the DAAQ grows much faster on the substrates with higher surface energies. Therefore, patterned growth of the nanowire arrays was achieved by modifying the substrate surfaces both geometrically and che...

InGaAs MOSFETs have been considered promising candidate for post-Si logic devices beyond 14nm technology node. To meet the increasing demand in electrostatic control at sub-100nm channel lengths, non-planar 3D structures have been introduced to the fabrication of InGaAs MOSFETs. In this paper, the fabrication and characterization of various non-planar 3D InGaAs MOSFETs have been demonstrated an...

A spatial potential trap is formed in a 6.0-μm Al(Ga)N nanowire by varying the Al composition along its length during epitaxial growth. The polariton emission characteristics of a dielectric microcavity with the single nanowire embedded in-plane have been studied at room temperature. Excitation is provided at the Al(Ga)N end of the nanowire, and polariton emission is observed from the lowest ba...

Lithographically patterned nanowire electrodeposition (LPNE) is a new method for fabricating polycrystalline metal nanowires using electrodeposition. In LPNE, a sacrificial metal (M(1)=silver or nickel) layer, 5-100 nm in thickness, is first vapor deposited onto a glass, oxidized silicon, or Kapton polymer film. A (+) photoresist (PR) layer is then deposited, photopatterned, and the exposed Ag ...

UNLABELLED Superior photon absorption in ordered nanowire arrays has been demonstrated recently. However, systematic studies are still missing to explore the limits of their implementation as functional photonic devices. With emphasis on silicon nanowires, we investigated the effects of nanowire diameter, length, morphology, and pitch on the photon absorption within the visible solar spectrum b...

Development of thin-film transparent conductors (TC) based on percolating networks of metal nanowires has leaped forward in recent years, owing to the improvement of nanowire synthetic methods and modeling efforts by several research groups. While silver nanowires are the first commercially viable iteration of this technology, systems based on copper nanowires are not far behind. Here we presen...

  In this work,copper/palladium (Cu/Pd) multilayer nanowires were successfully prepared by electrodeposition method using polycarbonate template. The fabrication of Pd/Cu multilayer nanowires was controlled by analyzing the current–time transient during electrodeposition using potentiostat. The morphological properties of the nanowires were studied by scanning electron microscopy (SEM) and resu...

The output of a piezoelectric nanogenerator based on ZnO nanowire is largely affected by the shape of nanowire. In order to obtain mechanically stable nanogenerator with high performance, the investigation of mechanical and electrical characteristics related to the nanowires and materials used in nanogenerators are of great interest and significance.
