Poster abstract

We investigate a silicon nanostructure which has never been seen before in order to unlock new material properties. The nanostructure consists of a thin layer of amorphous silicon containing vertical aluminium nanowires. These wires are easily removed, leaving a porous matrix of silicon. The uniqueness of this structure is the size of the nanowires, which are only 5 nm in diameter. At this scale new material properties, such as how light interacts with the material and how electrons behave in the material, are expected. This study uses world leading electron microscopy and other macroscopic techniques to explore the nanoscale world of silicon in hope of finding cheaper and more efficient materials for energy harvesting.
