Silicon NanoWires by MACE

The silicon nanowires at INRiM are extruded by a metal mask with MACE (Metal Assisted Chemical Etching) technique and covered by 40 nm of gold deposition. . [...]

Nanowires forest in winter

What appears as a snow cap is in reality a gold deposition on the tops of the silicon nanowires. [...]

Nanowires forest

Extruded by a holey metal mask, a residual is visible at the image centre, by means of a liquid chemical etching in HF and hydrogen peroxide.[...]

What are NanoWires?

Nanowires are structures in cylindrical form with straight or curved aspects. They have lengths in the range of a few micrometers [...]

Project overview

Energy harvesting from renewable sources (solar, heat and movement) is a prominent solution to create small amounts of electrical energy in areas of difficult access, and energy harvesting devices have much potential to address our world energy problems.

Nanowire (NW) based energy harvesting systems have achieved encouraging progress, but due to nanometre (nm) dimensions of the wires and large size (square meter) of the devices, they also bring challenges for testing and characterisation.

12 European Countries and Universities

17 Nanotechnology Laboratories

Support Europe's Future Demands for Renewable Energy

This project aims to develop reliable and high throughput metrology for the quality control of NW energy harvesting systems. Read more
