Abstract: A method of electrochemical deposition of a metallic material onto a substrate is provided. The method includes providing an alkaline solution of hydroxide ions, immersing a metallic material precursor and the substrate into the alkaline solution to form an electrochemical bath, and electrochemically depositing a textured layer of the metallic material onto the substrate. A method of electrochemical deposition of a textured nanoparticle is provided. The method includes providing an alkaline solution of hydroxide ions, immersing the metallic material into the alkaline solution to form an electrochemical bath, and precipitating the textured nanoparticles from the electrochemical bath.

Abstract: A method for electron beam lithography. The method may comprise fabricating a multi-layer mask and interposing the multi-layer mask between an electron beam and an energy-sensitive layer to thereby expose the energy-sensitive layer to the electron beam through the mask. Fabricating the multi-layer mask may comprises providing a first mask layer fabricated from a first mask material (e.g. silicon nitride) which defines one or more feature apertures corresponding to features of interest and coating an electron-energy-reducing material (e.g. gold) onto the first mask layer to thereby provide a second mask layer.
