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. This paper presents the various behavior of ...

A comprehensive study of the silicon nanowire growth process has been carried out. Silicon nanowires were grown by plasma-assisted-vapor-solid method using tin as a catalyst. We have focused on the evolution of the silicon nanowire density, morphology, and crystallinity. For the first time, the initial growth stage, which determines the nanowire (NW) density and growth direction, has been obser...

The elastic deformations in the conical nanowires are considered. An analytical expression was obtained for distribution of along length nanowire. It found that at certain cone angles nanowire there is an extended area sufficiently high comparable or even large than deformation base So, example, when bending (conical coefficient a=-0.7) with L=1 μm and radius R=50 nm by Delta z=200 nm, maximum ...

Thermal rectification based on a new strategy of nanostructuration has been assessed with nonequilibrium molecular dynamics and wave-packet propagation simulations. The use asymmetric crystalline-core/amorphous-conical-shell nanowires creates direction-dependent thermal conductivity due to variable axial radial phonon propagation/confinement. origin this effect is related the combination crysta...

We explore mechanical properties of top down fabricated, singly clamped inverted conical GaAs nanowires. Combining nanowire lengths of 2–9 lm with foot diameters of 36–935 nm yields fundamental flexural eigenmodes spanning two orders of magnitude from 200 kHz to 42 MHz. We extract a size-independent value of Young’s modulus of (456 3) GPa. With foot diameters down to a few tens of nanometers, t...

We present designs that enable a significant increase of solar absorption in ultra-thin (100–300 nm) layers of gallium arsenide. In the wavelength range from 400–860 nm, 90–99.5% solar absorption is demonstrated depending on the photonic crystal architecture used and the nature of the packaging. It is shown that using only two hundred nanometer equivalent bulk thickness of gallium arsenide, for...
