Analysis of GaN Grown on Vertically Standing Fractal-Like Si Nanostructures

Wee Q.X., Soh C.B., Zang K.Y., Chua S.J., Thompson C.V., National University of Singapore (NUS), SG

We have investigated the microstructure and optical properties of GaN grown on vertically standing Si nanostructures by MOCVD. The Si nanostructures array is formed by a simple metal-assisted etching of Si(111) substrates, where both metal [...]

Graphite Layer Nano-composites with Polyurethane Matrix

Czajka M., Shanks R.A., RMIT University, AU

The aim was to prepare expanded graphite oxide (GO, Graftech Inc.) and disperse it in a polyol (poly(oxypropylene glyceride), Dow Chemicals) using ultrasonication. The dispersion was polymerized and crosslinked with methane 4,4’-diphenyldiisocyanate to form a [...]
