Porous anodic alumina on galvanically grown PtSi layer for application in template-assisted Si nanowire growth

We report on the fabrication and morphology/structural characterization of a porous anodic alumina (PAA)/PtSi nano-template for use as matrix in template-assisted Si nanowire growth on a Si substrate. The PtSi layer was formed by electroless deposition from an aqueous solution containing the metal salt and HF, while the PAA membrane by anodizing an Al film deposited on the PtSi layer. The morph...

Capillary Force in High Aspect-Ratio Micropillar Arrays

High aspect-ratio (HAR) micropillar arrays are important for many applications including, mechanical sensors and actuators, tunable wetting surfaces and substrates for living cell studies. However, due to their mechanical compliance and large surface area, the micropillars are susceptible to deformation due to surface forces, such as adhesive force and capillary force. In this thesis we have ex...

Properties of Ni and Ni–Fe nanowires electrochemically deposited into a porous alumina template

The comparative analysis of the electrochemical deposition of Ni and Ni-Fe nanowires (NWs) into ordered porous alumina templates is presented. The method developed allows for obtaining NWs of 50 ± 5 nm in diameter and 25 μm in length, i.e., with an aspect ratio of 500. XRD data demonstrate the polycrystalline nature of Ni and Ni-Fe in a face-centered cubic close-packed lattice. Both fabricated ...
