in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...

High energetic ions can lead to the formation of long columnar defects along the ion trajectories, so called “ion tracks”. In amorphous metals, overlapping tracks produce macroscopic anisotropic growth phenomena [1]. Characterization and imaging of single ion tracks in these materials is challenging and has been successful only in a few cases using chemical etching [2], scanning probe [3] and t...

Introduction Single event effects (SEE’s) induced by heavy-ions from cosmic-rays are a major problem for the reliability of microelectronic devices in space environment. The energy deposited by a heavy-ion through the sensitive structure of a device produces, in a very short time, a dense concentration of electron-hole pairs along the ion trajectory. Generated carriers are collected by drift (i...

Irradiation of a solid with swift heavy ions can induce structural modifications in a very narrow region around the ion trajectories, so called ion tracks. In quartz, swift heavy ion irradiation leads to a change in the refractive index and offers a means to impose an etch anisotropy in the material, paving the way for nano-fabrication and micromachining of optical devices. Ion tracks in quartz...
